Cloud infrastructure & backend systems for fintech.

I help fintech teams design, ship, and operate reliable cloud platforms — from architecture and APIs down to the embedded edge.

About

I run trapcode.dev as an independent consultancy out of Rzeszów, Poland. By day I lead infrastructure at a fintech startup; the rest of the time I take on a small number of focused engagements where reliability and compliance aren’t optional. I work across the full path — cloud architecture, backend services, and the embedded devices that feed them.
