Hi, I’m Sylwester.

I help businesses build robust mobile apps.

My Approach

Robustness

An engineer’s core mission is to build solutions that simply work. End users value reliability — they want apps they can trust and that treat their time with respect.

Getting Your Hands Dirty

Proof of Concept beats theory every time — it reveals what works, what breaks, and where the real opportunities lie.
