As usual, your classes are epic. I think the first one I attended was a pre-conference SharePoint web part development at Dev Connections in the 2005-2006 timeframe. Your classes were awesome then and now! I have never been disappointed in any of your demonstrations or lectures over the years. Your examples and absolute thorough knowledge of the subject are always above approach.

I think the whole thing is great – a solid overview of what you need to know about. AC is one of those trainers who I try to never miss at conferences. Even if I have seen the session several times already, I always learn something essential each time, and I enjoy myself doing it.

Thanks for the great course, it helped me to bring my thoughts and explorations to a clear point. Each lesson of the course is not too vast and covers the exact portion of knowledge to understand what and how. I've been engaged in SharePoint for about 10 years, but the developer path was too complicated. Now as of SPFx released, I am starting my first steps. Walking through the email course and reading your blog posts helped me to clarify a few things and point out further actions. Now am going to master React and TypeScript to put them to use in my projects.

First day of ESPC means tutorial day 🙌, for me that means "Zero to Hero: Build Microsoft Teams Apps for Full Stack Developers" 🧑‍💻 with the one and only Andrew Connell (finally we meet in person) 👀 - really cool to catch up on some of the "I should look into that stuff" that's been on my list of stuff to learn for years 🎉

The [webinar series] was very well organized and does inspire me to go forward towards the certification. Your presentation style provide just the right level of detail I prefer tor receive along with plenty of reference material to guide for later.

DevFacto

At DevFacto, we've focused on developing SharePoint solutions for our clients for the past 12 years. We learned quite quickly that equipping our development team with the skills they needed to develop these same solutions in Office 365 and SharePoint Online wasn't going to be the same evolution we've seen with the traditional on-premise upgrades in SharePoint over the last 2 decades, and opted to leverage Voitanos to equip our entire team with the foundational skills to leverage this framework and eliminate the hurdles and time associated with each developer learning it one at a time. Voitanos was not only extremely economical but because the SharePoint Framework leverages many modern web development technologies including Node, ReactJS, gulp, and webpack, we leveraged this opportunity to train members of our traditional web development teams with how to use the technologies they were already using and apply those on SharePoint and Office 365 applications. The training was extremely well received by everyone involved, and as an organization, we were able to recoup the investment almost immediately through the increased productivity of our team.

I recently completed an 8-week course in Microsoft Teams AppDev Accelerator course with Andrew, and it was an outstanding learning experience. Andrew is highly regarded as one of the top instructors and professionals in the industry. His expertise and wealth of knowledge in M365 full-stack development were evident throughout the course. The course was exceptionally well-organized and comprehensive, providing up-to-date information in a cohesive manner. This structure allowed students to easily grasp the latest concepts and gradually build their skills throughout the duration of the course. Andrew's ability to effortlessly navigate complex technical discussions was remarkable, and his willingness to elaborate on and clarify questions made the content highly understandable, even for those of us who were relatively new to the topics. The course's design and pacing allowed us a full week to thoroughly study and comprehend each topic. Coupled with Andrew’s willingness to generously share his knowledge, this provided ample opportunity to ask questions, which greatly enhanced the learning experience. I feel incredibly fortunate to have had the opportunity to attend Andrew's course and learn from him. Every moment of the course was invaluable. This course not only expanded my knowledge and capabilities as a professional but also inspired me to continue exploring and offering advanced yet practical MS Teams solutions to my customers.

The accelerator was really valuable for me. I have done Teams development before but it was only using SharePoint Framework. I have not had a chance to explore the other options. This class helped me to reinforce what I already knew and introduced me to new concepts. As an SPFx developer, it was interesting to see other ways to solve business challenges for my clients and learn new skills. It was well worth not only the cost of the accelerator but also the time commitment. The class resources make it even more worth it. Some of the technology was new to me and Andrew did a great job of explaining the basics but for the things I had done before he had deeper content that helped me level up my game.

@ SMB Solutions Kft.

The technical aspect is well planned, so it goes from the overall picture to the detailed explanation. This is where I see your perfection in teaching and explaining things. You answered all the questions, showing that you are not only doing a webinar with pre-determined content but also a knowledge transfer. Every time I read or hear one of your content, I learn something or a topic becomes clearer. It happened today too: I understood how the LLM can be involved in a Teams Extension response, and where these extensions can be used. I'm already waiting for the moment when my manager allows me to sign up for one of his Teams App Dev courses.

I was using Voitanos' MS-600 Prep Course to prepare for the exam when Microsoft, one week before the end of my preparation, changed the topics of the exam. Andrew delivered the comparison of the new and the old content covered by the exam, which was enough to make a right change in my preparation process. This content is up to date and declares the themes you have to know.

Demir Dobric

Managing Director, Delta Access GmbH

I participated in a training session on Friday, and it was both engaging and easy to follow. If you're a developer looking for an overview of the possibilities available, it will be very helpful. I've been following Andrew for a few years now and have attended his SharePoint trainings too. He has a real talent for explaining concepts clearly and focusing on relevant content. Enjoy!

I like the newsletter because it gives me in one look, an overview of the latest news on SharePoint Online future-proof / cloud-ready development. It also serves for me as a ‘readers-list' to follow up on at a more quiet moment (‘bookmark').

I came to know about MS-600 exams through Andrew's free webinars for each of the five workloads. They clearly explain what you can expect from the certification and what resources you need to prepare yourself for the exam. There's nowhere else you would get such clear and detailed information on how to approach the exam, I'm waiting for Andrew's new course on the exam before I take the certification myself.

Shine Achuthan

Microsoft 365 Engineer

Andrew Connell did an outstanding job guiding us through complex concepts with a clear and straightforward step-by-step approach. While he covered an extensive range of topics, including some off-topic areas, he ensured that all my questions related to Copilot were thoroughly addressed. The recorded session proved to be invaluable, allowing me to revisit and clarify certain areas multiple times. Truly exceptional Shine

The course is amazingly in-depth and has tons of terrific content. Andrew does a great job of communicating complicated subject matter in a way that is easy to understand. I highly recommend it to learn and master the latest SharePoint Framework.

Retired!

Today is a great day for me because I finally get to retire. But I just wanted to send a word of thanks for all you have given to the SharePoint community. I've been doing SharePoint consulting since 2004 and you have always been a great resource for me. I've seen you at conferences, met you at parties, read your books, and followed your blogs. As SharePoint has changed through the years, you were always a go-to source with good insight and code examples. I just wanted to say thanks on my way out.

Far beyond the value of the actual course content that comes as part of the SPFx Ultimate Bundle (which is a lot), the access to the mastermind group that is just for Ultimate Bundle students and the community around that group make the Ultimate Bundle worth every single penny. The amount of time other students and Andrew Connell have saved me by being able to answer every question I throw at them is invaluable! There really is no other option I would recommend to anyone for SPFx training.

Participating in the 'Microsoft Teams App Dev Accelerator' course with Andrew Connell was a transformative experience. Over eight weeks, Andrew not only shared his extensive knowledge but also his passion for Microsoft Teams App development. His dedication was evident in every lecture, video, and office hour, guiding us through intricate topics like Tabs, Bots, Message Extensions, and AI integration. The course's comprehensive scope provided a solid foundation and a wealth of resources that I will continue to use in my professional journey. The camaraderie among the class made each session enjoyable and the entire learning process memorable. Andrew's unwavering support and the group's dynamic have certainly set this course apart. I'm grateful for the experience and excited to apply what I've learned.

Julie Turner

I absolutely got a lot out of the class and I learned a ton that I didn't already know... and I came in knowing quite a bit! What will be most valuable is that now that I have a solid understanding of the development environment the components, and the concepts when I start applying what I learned to production projects and think “oh, I forgot... what the heck is this part?”... I have all the content from the course to go back to and can quickly jump to the session recording, office hours recording, or lab source code that covered the topic. Having that resource so easily accessible, plus a network of peers from the community created from the extended format of this course... that's the sort of "just-in-time learning" that makes this class a value by any standard. Thank you!

Andrew provides a wonderfully down-to-earth presentation of technical topics. His frank commentary about what works and what doesn't in this Microsoft Teams App Development OnRamp course cuts through the M365 marketing hype targeted at developers and helps us quickly hone in on development methods that deliver results. I recommend the Microsoft Teams App Development OnRamp and Andrew's other works as a way of staying up-to-speed with what matters.

Michelle Rose

The "Microsoft Teams App Development OnRamp" email course is incredibly informative and well-structured. It breaks down complex concepts into digestible segments, making it easier for beginners to understand and for experienced developers to enhance their skills. The step-by-step guidance, combined with practical examples, ensures learners can apply their knowledge effectively. Additionally, the course's interactive elements and resources are exceptionally helpful in reinforcing the material. Overall, I believe this course is an excellent tool for anyone looking to master app development within Microsoft Teams. Thank you for the informative information!

The Microsoft Teams App Development OnRamp is an ideal way for professional developers who have been building Teams Apps for a while to check their knowledge and discover functionalities they weren't aware of or need to brush up on. The OnRamp series provides bite-sized daily emails, starting with the basics of Microsoft Teams App development and moving on through various Teams features and development concerns. Andrew provides a wonderfully down-to-earth presentation of technical topics. His frank commentary about what works and what doesn't cuts through the M365 marketing hype targeted at developers and helps us quickly hone in on development methods that deliver results. Microsoft 365 development is an always-evolving area. I recommend the Microsoft Teams App Development OnRamp and Andrew's other works as a way of staying up-to-speed with what matters.

I recently attended Andrew Connell's live workshop, "Build Declarative Agents for Microsoft 365 Copilot," and it was an incredibly valuable experience. The workshop covered everything from understanding the out-of-the-box capabilities of Microsoft 365 Copilot to creating custom plugins and integrating real-time relational data. Andrew's detailed exploration of practical use cases and hands-on execution made complex topics accessible and actionable. I now feel confident in leveraging AI to enhance our organizational systems. Highly recommended for any Microsoft 365 full-stack and web developers looking to maximize their Copilot investment!

Evans E

SharePoint Architect/PowerApps Developer

Andrew's course has been instrumental in deepening my understanding of the SharePoint Framework, providing clear explanations, practical insights, and real-world applications that have significantly improved my skills and confidence. I have successfully applied my knowledge to both work and personal projects, enhancing problem-solving efficiency, improving decision-making, and delivering better overall results. I'm eager to take future courses in SharePoint, Office 365, and hopefully AI, to continue expanding my expertise and staying up to date with emerging technologies.

Jason Ing

I'm an autodidact who loves to learn independently rather than attend traditional classes. So, taking Andrew's workshop was a rare event for me. I expected to either hear something I had already encountered on the internet or eventually learn about it elsewhere. However, what I experienced was an entirely positive, organized, and professionally presented subject matter tailored for professionals. I was able to interact and get immediate answers in a live setting. Most importantly, the workshop's value made the cost worthwhile, as I gained access to information that could not be found elsewhere, thanks to Andrew's industry experience and network connections. Thank you, Andrew!  “jaji”

I thought the webinars were great in getting the info across on everything required for study - I had no idea at the time there was so much material available, and it was really good quality! As a result of studying it, I passed the exam first time.

Our organization has leveraged Andrew's knowledge and services as a 1:1 coach for our application development team. His insight and advice have been invaluable. When it comes to the M365 development stack and tools, you will quickly learn there are a lot of gaps in the official documentation. We tried working with Microsoft to get clarity and answers but were unsuccessful. Andrew fills a much needed gap, both from an information and service standpoint, as well as liaisoning with Microsoft on behalf of developers who are using the M365 stack.

I am beyond thrilled and deeply grateful for the opportunity to have been part of the inaugural cohort of the App Dev Accelerator. This program surpassed all my expectations, offering a wealth of in-depth knowledge that, despite its complexity, was presented in a remarkably digestible and well-paced format over eight weeks. The unanimous praise from my fellow classmates is a testament to the course's exceptional value. Andrew, our instructor, was particularly remarkable in his dedication to ensuring no one was left behind. His commitment to our understanding and mastery of each topic before moving forward was truly commendable. This experience has been transformative for me, both personally and professionally. My newfound confidence and skills, honed in this program, have led me to enroll in the Microsoft ISV program before we had even finished. I am now eagerly applying everything I've learned as I embark on this exciting journey. I am already in the process of submitting my first few apps to the app store, a step I might not have had the courage to take without the solid foundation and confidence gained from this course. I eagerly anticipate seeing my apps live before the year's end, marking the start of a thrilling new chapter in my professional journey.

Cheryl de grasse

M365 Solutions Architect

I joined the Voitanos Microsoft Teams AppDev accelerator course to understand next-gen development in the Microsoft 365 collaboration platforms after being in nontechnical roles for many years. Andrew has been able to fast forward my understanding, has personally helped me with setting up a usable learning environment, and keeps the whole class (including alumni) updated with real-time changes in the Teams and related AI development space. His evergreen program will future-proof my technical understanding as well. I highly recommend Voitanos for people wanting to hone their development skills, or anyone in an architect role to learn what is possible, what actually works, and what is hype.

I can confidently say that if I had to make the decision again, I would absolutely choose to participate in this accelerator. I highly recommend this training to anyone interested in gaining a deeper understanding of Microsoft Teams development. Your knowledge and ability to explain even the most complex concepts in a simple and cohesive manner are truly remarkable. You are an outstanding instructor, the best I’ve had the pleasure of learning from. Thank you again for this opportunity!

Passed MS-600 exam today. All the workloads in the certification are complex on their own and technically evolving every day. With teams very novice, JavaScript Office add-ins. No Idea!, and like this many gaps before preparation. Thank you for the comprehensive course which kept focus to pass the exam with excellence (858). As promised!

@ Nodero

First I want to thank you for producing this course. I really like the way the information is presented and you are fantastic to listen to. It's obvious how much you know, and that a lot of thinking went into how you've broken it down. The duration of each video is perfect - focused details, easy to consume info but doesn't drag on, and I've often gone back and re-listened to parts. Great that key topics within each video are marked. You've done an amazing job! 🙂🙂

This SPFx course has been an incredible learning experience. It provides a strong foundation while also diving into advanced topics, making it a valuable resource for developers at all levels. The material is well-structured, covering both high-level concepts and hands-on development, ensuring a comprehensive understanding of SPFx. One of the standout aspects of the course is the breadth of content—there are plenty of in-depth modules that reinforce the fundamentals, making it easy to build a solid knowledge base. I’m looking forward to revisiting some of the foundational courses to refine my expertise even further. Overall, this course has been a fantastic investment in my SPFx journey, and I highly recommend it to anyone looking to expand their SharePoint development skills.

Thanks to the team at Voitanos, I aced the MS-600 exam. What I appreciate about Voitanos course material is their focus on exactly what you need to know, what you don't need to know, and the material is frequently updated to keep content fresh and relevant. Andrew is a great course author and instructor. I'm looking forward to what he and his team produce next!

I am super excited to have found Andrew Connell, the topics he is teaching completely align with my goals. Currently going through his Understand the SharePoint Framework Toolchain (email course), which is very informative. Also love that he is teaching you to be ready to build webpart etc instead of sending you to go learn JavaScript first direction and that takes you in another direction. His method is very fine-tuned to make you a SPFx developer and what skills are needed to do just that. Again, thank you, Andrew, really appreciate what you are doing!

Thanks to the excellent content and training provided by Voitanos I passed the MS-600 exam!  You provided a realistic expectation of the complexity of the exam, what was and was not on the exam, and great resources for us to follow up with for topics we needed additional training on.  With the constant changes to the exam, you did an amazing job keeping the content fresh and relevant. While I had to put in the time and effort to study the concepts and related resources, there is no way I would have passed without your guidance on what I needed to know. I watched the videos many times and picked up additional information each time. Your cadence, visuals, and tone of voice were pleasant and understandable. Your delivery was more enjoyable than many audiobook narrators I have listened to. The course was of a higher quality and better than any live instructor-led training and your depth of knowledge and enthusiasm were clear from the first video.  There is nowhere else that you find such a clear and comprehensive course. If you choose to produce any future exam prep courses, I will turn to you first and direct any of my friends or teammates to you as well. I am looking forward turning my focus onto your Mastering the SharePoint Framework Ultimate bundle and what you produce next!

DMI (Digital Management, LLC)

I can’t speak highly enough about Andrew's latest Accelerator! The format of the course is perfect for the busy Professional Developer. Breaking down the instruction into smaller blocks over multiple weeks allows the incredible content to be absorbed fully instead of the typical information overload that happens often in other “live” developer courses. The live instruction is reinforced with self-paced videos that walk through building actual applications which allowed me to better understand what I had learned earlier in the week. Office hours encourage all students to ask questions and learn from each other in addition to Andrew. Limiting the class size to a small group promotes interaction by all of the students in the class and the value of the content was further emphasized in our course as students participated in the live sessions from all corners of the planet, often in the middle of their night. Andrew's approach to learning further establishes him as one of the premier trainers anywhere in the world. His relentless pursuit of the deepest understanding of the entire development toolkit allows him to explain Teams development at every level and his joy is obvious when he can use this deep knowledge to better help students understand the subject matter. In many cases, these discussions identified where the tools could be improved and our feedback was heard by Microsoft. Andrew’s close relationship with Microsoft and the development teams that build these products gives him unmatched knowledge and access to the training space. Coupling that with his real-world experience building enterprise-level solutions for customers allows Andrew to deliver relevant content that developers need to know and understand to produce first-class professional applications. This course takes you all the way to the 300-400 level experience! Your potential as a developer in the Microsoft space will be unleashed as the course covers so many areas; not just Teams, but Azure, Entra ID, the app store, and so much more. Thank you to Andrew and my fellow cohort students for a one-of-a-kind world-class experience. I am excited to continue building relationships with this amazing group of professional developers, including Andrew.

Jennifer Eckard

I was able to get through the overview today and start the first chapter, which I must say I am excited about. I have not done any Office add-ins primarily because SharePoint, Teams and the Power Platform have kept me busy. I know about them and am glad that you have put the resources out there in an organized manner so that I can do a deeper dive and learn more. I understand that this course won't make me an expert but you have given me the tools to learn more about it which I greatly appreciate. I enjoy self-paced learning. I also wanted to state that you did a great job explaining what it is like to take an exam from home.

I chose to participate in Andrew's new Microsoft Teams App Dev Accelerator class and was not disappointed. The content of the course is thorough, comprehensive, and as up-to-date as it can be in the dynamic and rapidly-changing environment that is MS Teams app development. Andrew's teaching style is engaging and he is very good at breaking down complex technical details to make them more understandable. Additionally his deep well of experience and familiarity in the industry, as both insider and outsider, meant that I could trust his opinion when questions arose that were not always strictly technical. Being able to press him on developer-related issues has been invaluable to me, perhaps even more so than the outstanding technical content that was presented. Meeting with Andrew and my exceptionally sharp, curious, and talented classmates regularly was a very positive professional experience. I would recommend this course for anyone interested in building web applications capable of running within (and taking advantage of) the MS Teams environment.

I just attended the Microsoft Teams Accelerator course and it was fantastic!

🚀 RACING TO STAY AHEAD I recently attended the Build Declarative Agents for Microsoft 365 Copilot workshop by Voitanos, led by a fellow auto racing enthusiast and M365 expert Andrew Connell, and it was a great learning experience. I joined the workshop to understand better the M365 Copilot extensibility story of AI Agents using the development tool stack, with the latest insights in the industry post-Ignite, and it delivered exactly what I was looking for. From incorporating real-time data into your Agents to integration scenarios with Microsoft Graph, the content was great and gave me a better understanding of the quickly changing landscape so that I could better assist my partners and clients!
