Hi, I'm Paweł Ludwiczak – a Product Design Engineer. I turn ambiguous problems into shipped software.

I help founders and technical teams shape useful, coherent products – from early thinking and first sketches to polished interactions and production-ready frontend. 15+ years across design and engineering, one owner from idea to shipped software.

My strength is judgment – built at Stack Overflow, Canva, and a decade of startups: finding the real constraint, deciding what matters, simplifying without losing the idea, and caring about every state and interaction. AI helps me research, prototype, build, and test faster – but it doesn't make the decisions. I do.
