Testimonials
“I'd heard a lot about Cursor AI but struggled to get started on my own—worried I'd miss important features or not learn it properly. That's why I joined the WarsawJS Jam, and honestly, it was the best decision! I joined the beginners group with Kacper Wikieł as our coach. At first, it all felt overwhelming—LLMs, prompt engineering, everything. I'm more used to writing code than prompts, though I do use GitHub Copilot at work. But Cursor AI's prompt-based approach felt like a different world. It was a bit strange at first, but with Kacper's guidance and a hands-on task, things started to click. Step by step, I built an image-generating app with a slick UI, deployed on Vercel. Seeing the final result was incredibly satisfying! Kacper didn't just teach Cursor AI—he introduced us to a bunch of other tools and shared valuable insights to explore further. I came to learn the basics through a practical example and left with much more. I'm definitely joining the next workshop—it's a great learning environment, not just because of the coaches, but also the other participants. Highly recommend it if you want to dive into Cursor AI with support and inspiration!”
“Szkolenie było naprawdę świetne! Bardzo konkretna dawka wiedzy, podana w przystępny sposób. Pokazano realne przypadki użycia Cursor AI w codziennej pracy developera – pokazano b. praktyczne podejście. Naprawdę otwiera oczy na to, jak można usprawnić swój workflow i oszczędzić mnóstwo czasu. Uważam, że to must-have dla każdego software developera :) !”

“Przed szkoleniem nie miałem za bardzo styczności z CursorAI więc nie byłem świadom tego, jak dużo można zrobić dosłownie w ciągu kilkunastu minut przy pomocy tego narzędzia. Kacper, prowadzący to szkolenie, przekazał w ciągu kilku godzin bardzo dużo wiedzy teoretycznej i praktycznej, dzięki czemu moje horyzonty programistyczne dosyć mocno się poszerzyły. Polecam każdemu!”
- Paweł Wojtecki
“Kacper is turbo-intelligent guy, willing to share his knowledge and experience with others. It's really worth to attend his workshops!”
“I'm glad I got the chance to participate, it has already changed my mindset and view on the future of development and my career.”
