Bartlomiej Sarnecki.

I'm a senior engineer based in Wrocław, Poland. I build across the full stack — from database design to CI/CD infrastructure. I work best on teams that value directness, good tooling, and getting things shipped.

Since 2021 I've worked independently, taking on a small number of projects at a time. Clients have included early-stage startups, scale-ups, and engineering teams at larger companies that needed external perspective or extra capacity.

Outside of client work, I write occasionally about software engineering, infrastructure, and the operational side of building things.
