Real projects, shipped for real clients.
A selection of websites and apps I've designed and built. Each one started as someone's idea and ended up live on the internet.
Hire one person. Ship like a team.
From a first idea to a live product, I cover the whole build: design, development and the AI that makes it smart.
Web & app development
Fast, responsive websites and web apps built with modern tools. From a polished landing page to a full product: clean code, great UX.
- Next.js / React
- Responsive & accessible
- SEO-ready

Creating since
elementary school
A developer who's been building things since childhood.
I'm a 21-year-old developer from eastern Slovakia, now based in Bratislava. My path started early. I picked up video editing in elementary school, and that curiosity kept snowballing into design, web development, programming and, most recently, AI.
Today I study Applied Informatics at the Faculty of Mathematics, Physics and Informatics (FMFI) at Comenius University in Bratislava while freelancing for clients around the world and building my own startups on the side. Years of remote projects taught me the thing that matters most: understanding what someone actually needs, moving fast, and shipping work I'm proud of.
Right now I'm focused on building AI-powered apps and tools, the kind that quietly save people hours. If you have an idea, I can help you turn it into something real.
