Who We Are

ABOUT

👤
YOUR PHOTO
Mateusz WitkaFounder & Full Stack Developer

I build websites and online stores that actually work. I'm a full stack developer, and I handle every project personally, from architecture to server deployment, with no outsourcing and no agency middlemen.

Stronorob isn't a corporation. It's one person who treats code as a precision tool, not an assembly-line product. You talk directly to me at every stage.

V_01Directness

You talk to me, not to a project manager.

V_02Precision

Architecture that is thought through, not glued together from ready-made parts.

V_03Accountability

A one-year update guarantee is a concrete commitment, not a marketing gimmick.
