About

I'm a software developer from the Czech Republic who likes to take ideas all the way — from an empty repo to a product people actually use. I care about clean architecture, fast, accessible interfaces and shipping.

Outside of building, I create content and stream development live on YouTube, Twitch and Kick — sharing the real process, the bugs included. If you're building something interesting, I'd love to hear about it.

Based in Czech Republic.

kphub.cz

A Webnode-style platform where I take a client site from idea to MVP all the way to deployment on Cloudflare Pages — built end to end with TypeScript frameworks on both frontend and backend. Each client lives on their own subdomain; live examples include vlastimilpelcak.kphub.cz and kskromeriz.kphub.cz.
