Real-world engagements this covers

A typical Poland brief

A Warsaw product studio adding BLIK payments while delivering for Western European clients.

Internal knowledge assistant

Your docs, wiki, and tickets become a searchable assistant that answers with citations — and says 'I don't know' instead of hallucinating, enforced by a relevance gate.

Customer-facing support bot with guardrails

Retrieval over your help centre with measured quality: an eval harness (hit-rate, MRR) runs on every change, so you know retrieval works before customers do.

Hybrid search upgrade

Pure vector search misses exact terms; pure keyword misses meaning. I ship hybrid retrieval (BM25 + vectors fused with RRF) plus LLM re-ranking — in my public benchmark this lifted MRR from 0.969 to 1.000.

What to look for in a rag developer

  • An eval harness — anyone who can't measure retrieval quality is guessing
  • Hybrid retrieval experience (BM25 + vector + re-ranking), not just 'call the embeddings API'
  • A story for hallucination control: relevance gates, citation grounding
  • Provider-agnostic design so you're not locked to one model vendor

FAQ

How much does it cost to hire rag developer in Poland?

Senior engineers in Warsaw and Kraków typically earn PLN 20K–30K per month on B2B contracts. Polish agencies commonly quote €40–80/hr. Typical remote rag developer projects with me run $25K–$150K depending on scope, billed in PLN or USD on fixed-scope milestones — you approve each milestone before it's built.

Do you work with clients in Poland?

Yes. I work remotely with Poland founders, product teams, and agencies — from Warsaw, Kraków, and Wrocław to fully distributed teams. English-first communication, contracts via Upwork or a direct SOW.

How does the timezone difference work with Poland?

Live overlap across your full business day — roughly 9 AM to 6 PM CET. Weekly demos are scheduled in your hours, and async updates keep the thread moving between them.

How do contracts and invoicing work for PL companies?

Cross-border B2B invoicing with reverse-charge VAT — the contract model Polish teams already use daily. Payment terms are milestone-based — no large upfront commitments.

Who owns the code and IP?

You do — completely. Work happens in your repositories where possible, IP assignment is written into the SOW, and there is no lock-in: everything is documented so any developer can take over.

Can you ship mobile, web, and AI together?

Yes. React Native + Next.js + Python (FastAPI) + RAG/AI agents under one senior owner — ideal when your Poland team needs to ship mobile, web, and AI without coordinating multiple vendors.

What happens after launch?

Most clients keep a monthly care retainer: dependency updates, store submissions, monitoring, and a priority line for fixes and small features. You can also hand off entirely — the documentation is written for that.
