Hire FastAPI Developers
- Senior Python engineers, async-first
- Fixed price per project · no hourly billing
- Engineer assigned within 7 business days
Hire FastAPI developers who build async Python services for production, not demos. Our engineers write correct async code with asyncio, call third-party APIs with aiohttp and httpx, validate everything with Pydantic, and ship APIs that are typed, tested and observable. Hire a dedicated FastAPI developer for months, or bring us in for a fixed-scope project.
Built for teams that need senior engineering — fast.
- US startups that need a dedicated FastAPI developer without a long recruiting cycle
- Teams moving a Flask or Django REST API to async FastAPI
- AI products that need a fast Python API in front of LLMs, RAG or agents
- CTOs whose async code blocks the event loop and falls over under load
Concrete deliverables. No bench-warming.
Async APIs done right
async/await end to end, no blocking calls in the event loop, proper connection pools for Postgres (asyncpg / SQLAlchemy 2.0 async) and Redis.
asyncio + aiohttp expertise
Concurrent fan-out with asyncio.gather and TaskGroups, timeouts and cancellation, aiohttp / httpx clients with retries and backoff. If you searched for an asyncio or aiohttp programmer, this is the work.
Typed contracts with Pydantic
Pydantic v2 models, generated OpenAPI docs and typed clients for your frontend, so API changes are caught before production.
Auth, background jobs, websockets
OAuth2/JWT, API keys, rate limits, Celery / ARQ background workers, websockets and server-sent events for streaming LLM responses.
Testing + observability
pytest with async fixtures, contract tests, OpenTelemetry tracing, structured logs and Sentry, so you see problems before users do.
Deploy and scale
Docker, Uvicorn/Gunicorn workers, AWS / GCP / Fly, CI/CD pipelines and load testing before launch.
Pick the shape that fits.
Dedicated FastAPI developer
A senior FastAPI engineer dedicated to your product for 3+ months. Your Slack, your standups, your code review.
Project-based
Fixed scope, fixed price. A complete API, service or migration delivered on a written timeline.
Retainer
Ongoing backend capacity for features, performance work and keeping the API healthy.
Audit + rescue
Review of your async code, database access and deployment, with a remediation plan.
Tools our FastAPI engineers reach for.
Common questions about hiring FastAPI engineers.
Can I hire a dedicated FastAPI developer?+
Yes. Our dedicated model puts one senior FastAPI engineer on your product full-time for 3+ months, working in your tools with at least 4 hours of overlap with US-East business hours.
Do your FastAPI developers know asyncio and aiohttp?+
Yes. Async Python is the core of FastAPI work. Our engineers use asyncio for concurrency, aiohttp or httpx for outbound HTTP, and know how to avoid blocking the event loop with sync database drivers or CPU-heavy code.
How much does it cost to hire FastAPI developers?+
Most initial FastAPI projects with us fall in the USD 3k–15k+ range depending on scope. Dedicated monthly engagements are quoted as a fixed monthly fee per engineer — no hourly billing.
Can you migrate our Flask or Django API to FastAPI?+
Yes. We usually migrate route by route behind the same URLs, add Pydantic models and tests as we go, and switch traffic once each endpoint matches the old behaviour.
Can we interview the engineer first?+
Yes. We send 1–2 candidate engineers for a 30-minute interview each, and you pick the fit before anything is signed.
