"Joris has helped us tremendously in professionalizing our software solutions. He is highly knowledgeable about the best practices and developments in the field and is able to communicate this in a clear, structured way. Without Joris, Syntro would not have been able to deliver the level of quality that we now consider standard."

"Joris did a great job in preparing complex dashboarding for our business. He was quick to understand our needs, responded quickly, and solved issues quickly even though he was doing another full time project on the side. Really happy he has supported us and would definitely work with him again."

"Joris is an outstanding professional. I have worked with Joris for several years, and I can honestly say he can deliver on anything he sets his mind on. Whether it's his interactions with programmers, demonstrating software, or generally delivering on targets, he always performs with excellence."

"Joris is super friendly and was really flexible in tailoring the sessions on what my purpose for learning is. He is giving me the direction I need to continue this journey, and I would certainly recommend him to anyone interested in taking Python to the next level."
