Viktor Vojtek

Fifteen years of shipping, from PHP to shaders.

I’m a full-stack engineer from Košice, Slovakia. I started in 2011 writing PHP for e-commerce, moved to the front end, and spent most of the last decade building products across web, mobile and AR: a furniture aggregator with its own AR app, a trivia social network, a virtual glasses try-on running on three.js.

Since 2024 I build my own products and take on a few client engagements a year. TypeScript, React and Next.js on the web, React Native and Flutter on phones, three.js, ARKit and ARCore when the pixels need to exist in the room. I like a small, boring stack, a real database and shipping every week.
