Adrian Zapłata - AI Engineer · Berlin, GERMANY (Open to relocation to Poland)
Shipping AI Systems - not demos.
RAG pipelines, LLM agents, structured extraction, workflow automation - production AI built on 7+ years of engineering. Helping teams adopt AI safely using local or cloud models, secure by design. Claude Code power user. Open to AI Engineer roles - remote / worldwide.
Proof of work
Seven years shipping production software - now aimed at one thing: LLM systems that survive contact with production. Retrieval, agents, evals, observability - designed, built and deployed end-to-end, solo.
Six AI systems shipped with tests, evals, guardrails, RAG and CI/CD. One local model trained with LoRA.

The agent
Don't read the résumé. Ask the model.
A small agent grounded on my background. Ask what I build, where I'm strong, what I'm looking for - it answers from the same bio a recruiter would read, minus the patience.
It runs on the same stack I'd ship for you: a Cloudflare Worker, prompt-cached Claude, rate limits, a spend cap, and every ask logged to D1.
Anonymous prompts may be logged to improve answers. No IP or identifier is stored.
