Krzysztof Kocot — Full-Stack Developer
Available for work

Hi, I'm
Krzysztof Kocot

I build modern web and mobile applications using AI-powered development workflow. Clean code, excellent UX, faster delivery. Working remotely from Katowice, delivering solutions for clients worldwide.

Passion for creating digital solutions

I'm a Full-Stack Developer with over 3 years of commercial experience. I independently design and build complete web and mobile applications — from database to UI.

With AI-powered systems I've built into my workflow, I deliver projects faster and at a higher quality than traditional development allows. Claude, Gemini, and custom automation handle the repetitive work — I focus on architecture, business logic, and the details that make software feel great.
