About me

I'm a fullstack engineer based in Poland. Over the past six years I've shipped production features across DeFi protocols, e-commerce platforms, and design systems — owning the full picture from schema and API design to the interface that users actually touch. I care about UX enough to push back on a spec, and about DX enough to make sure the next engineer has a good time. What sets me apart isn't just writing code that works — it's the attention to quality at every layer of the stack.

What I bring

Attention to Detail

I notice what others skip — in interfaces, in logic, in specs. Transitions, edge cases, and silent assumptions that turn into bugs. The gap between functional and correct is where I pay the most attention.

Fullstack Delivery

I can take a feature from an empty schema to a working UI without handing it off. That means fewer gaps, faster iteration, and someone who actually understands the whole thing.

Developer Experience

I build systems other developers enjoy working in — clear conventions, solid tooling including context-aware AI agents and documentation that saves hours of confusion.

Performance

Profiling, measuring, and shipping — never guessing. Fast for every user on every device, without trading off the polish.

Learn, validate, repeat

Writing is how I validate what I think I know — and find out what I don't. I cover software engineering, web development, and the ideas shaping how I work.

Get in touch

Open to new roles, interesting side projects, and conversations worth having. If you're building something ambitious — or need someone who'll care as much about the interface as the architecture — I'd like to hear about it.
