Vemund Fredriksen
“Marek and Vadzim deliver the information with confidence, referencing real-world experience throughout. The structure and flow are very streamlined, which makes it easy to follow complex concepts. The course fits everyone from junior developers seeking exposure to modern architecture principles to seasoned tech leads and architects who want an overview anchored in real-life experience.”
Håvard N
“Due to Marek and Vadzim's expertise and thoroughness in the field, I have filled some of the gaps I wasn't aware of having, too! The trainers were very professional and pulled off an excellent three-day session. Highly recommended.”
Johan-Henrik Fylling
“Marek and Vadzim spend as much time on the reasoning as on the patterns themselves, and are clear that every decision comes with pros and cons. You leave with a sharper sense of when and why to reach for each one.”
