Enrico Razzetti
“This course will satisfy both hardcore developers (many examples of code are presented) and IT project advisors, providing a solid, historically correct overview of several possible approaches to architecture and proposing many modern useful tools, with the intent of enabling the listeners to make a sensible choice in regard to their specific business case. This was good fun!”
Ivar Ness
“What stands out is how Marek and Vadzim teach. They bring experience from real projects, and it shows. They discuss trade-offs and explain context, not just throw patterns at you. Their examples relate to actual situations, which makes the content easier to apply. They are good communicators and keep the courses engaging. I have also met them at conferences, and their willingness to discuss ideas extends beyond the classroom.”
Ronny Mandal
“Finally, the instructors were clearly experienced practitioners. Their teaching was enriched with anecdotes and lessons learned from real projects, which helped ground advanced topics such as tactical DDD, CQRS, event sourcing, system stability, security, and monitoring. Overall, this was a well-structured, insightful, and highly applicable course that I would strongly recommend to architects and senior developers working on complex systems.”
