Freelance software engineer in Warsaw. I've been building and running production web apps for 20+ years, mostly with Rails and Postgres. These days I also ship in Rust, Go and Swift, with AI agents doing much of the typing.
I'm available for new projects. I build web apps, fix the ones that got slow or fragile, and help teams get real results from AI agents.
New: AI Workflow Session. A 90-minute, hands-on workshop for you or your team. We look at how you work with AI coding agents today and set up a more productive workflow together, in your own codebase.
- RAWmakase: a free, fast, Lightroom-compatible RAW photo editor for Linux, macOS and Windows. Written in Rust, built with AI agents that verify their own work.
- Omafeed: an RSS feed reader for Omarchy.
- ActionBar: a menu bar app for GitHub Actions.
