Real-world engagements this covers
A typical Portugal brief
A Lisbon startup shipping a React Native app on a FastAPI backend.
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.

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 Portugal?
Senior engineers in Lisbon typically earn €50,000–75,000. Portuguese agencies commonly quote €50–90/hr. Typical remote fastapi developer projects with me run $20K–$100K depending on scope, billed in EUR or USD on fixed-scope milestones — you approve each milestone before it's built.
Do you work with clients in Portugal?
Yes. I work remotely with Portugal founders, product teams, and agencies — from Lisbon and Porto to fully distributed teams. English-first communication, contracts via Upwork or a direct SOW.
How does the timezone difference work with Portugal?
Strong overlap with both Europe and the US East Coast — full European day, plus US mornings. Weekly demos are scheduled in your hours, and async updates keep the thread moving between them.
How do contracts and invoicing work for PT companies?
Cross-border B2B invoicing within the EU — straightforward, no local payroll. 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 Portugal 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.
