Building things for the web since 2009
Full-stack developer from Prague with over 17 years of building web applications and services. Co-founder and main developer of Testomato and long-time lead developer of Zdroják.cz, working mostly in PHP and TypeScript. I like small, efficient teams and products that stay simple.
I'm a full-stack developer from Prague with over 17 years of building web applications. I co-founded Testomato, a SaaS platform for website monitoring, where I'm the main developer, and have led development of Zdroják.cz, a Czech developer magazine, for more than a decade. I work mostly in PHP and TypeScript across the whole stack and use AI tools like Claude Code and Codex every day.

Freelance full-stack web developer working with PHP, JavaScript, TypeScript, Node.js, Astro, Vue, React, Tailwind CSS, Docker, and a wide range of technologies across the web development stack.
