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.

Ariadne

Memory layer for LLM agents. The repo says what the code does, Ariadne holds why it looks that way.

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.
