Solve

There are no unsolvable technical problems.

I firmly believe that all technical problems in software development are solvable. Most of the time when a problem feels impossible to solve, the question is, what kind of trade-offs are you willing to make?

This does not mean every problem has a technical solution though, organizational and social problems should not be solved with code.

AI Integration

I can help you integrate AI into your workflow. Whether that means building a document pipeline, LLM integration or getting everyone up to speed in your team, I got you covered.

Master's Thesis Research

I investigated whether RAG can work effectively without embeddings. The result was a strong Yes - full-text search can deliver better results in many cases, with significantly less infrastructure overhead.

Working With Me

Direct

No middlemen. I work directly with you to understand the problem and implement a solution for it. I'll tell you if something won't work and suggest alternatives.

Solutions

Complexity doesn't intimidate me. I've worked with codebases of all ages and quirks — the approach always adapts to the problem.

Network

As a proud partner in the Rabbit Hole Group I have access to a pool of talented people to solve every challenge - designers, DevOps, security, legal, hardware.
