I build tools I want to use.
Backend, data and search, Warsaw
Based in Warsaw. Most of my work sits under the interface: data models, search, and deciding where the boundaries between services go. Right now I'm building Ariadne, a memory layer for LLM agents.
Skills
From the data layer up to the interface. I build whole systems, not single pieces.

Featured projects
Selected work. The rest is on GitHub.
Ariadne
Memory layer for LLM agents. The repo says what the code does, Ariadne holds why it looks that way.
Ritatu
A macro tracker for Android I built after getting fed up with apps like Fitatu, overpriced and the AI barely works.

Hello!
I'm Stanisław. I build systems and learn as I go.
I think about data models, search quality and where the boundaries between services should sit. Lately that means memory: what gets stored, how you find the right piece of it later, and who is allowed to read it. Still learning, but the projects work and I own every decision in them.

Let's
talk.
I build backends, search and the systems around them. If that's the kind of thing you're working on, write.
