Real-world engagements this covers
A typical Poland brief
A Warsaw product studio adding BLIK payments while delivering for Western European clients.
Production API from a spec
OpenAPI-documented endpoints with JWT auth, rate limits, structured logging, and green CI — deployed to your cloud with zero-downtime releases.
Async performance rescue
An API that falls over under load. I profile, fix blocking calls in async routes, add connection pooling and caching, and load-test the result.
AI/streaming backend
Server-sent events for token-by-token LLM streaming, background embedding jobs, and provider-agnostic model routing — the exact architecture of my open-source RAG starter.
What to look for in a fastapi developer
- →Deep async understanding — blocking a FastAPI event loop is the classic footgun
- →Pydantic v2 models as contracts, not an afterthought
- →Real deployment stories: Docker, migrations, health checks, rollbacks
- →Tests that run without API keys or network access

FAQ
How much does it cost to hire fastapi 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 fastapi developer projects with me run $20K–$100K 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.
