Hire FastAPI Developers Who Keep Your APIs Fast Under Real Load
Hire FastAPI developers from Entrans who write async Python that holds up when traffic spikes. Our senior engineers build REST APIs, microservices, and LLM backends with Pydantic v2, async SQLAlchemy, and clean OpenAPI contracts. You get vetted profiles in 24 to 48 hours and onboarding within 48 to 72 hours.
Why Market Leaders Choose Entrans FastAPI Developers
FastAPI makes it easy to write an endpoint. It also makes it easy to write one that blocks the event loop and stalls every request on that worker. When you hire a FastAPI programmer from Entrans, you get an engineer who knows the difference and has shipped async services to production.
1. Async Skills Tested Before You Interview
We screen every candidate on async and sync boundaries, blocking calls, and database sessions under concurrent load. You meet engineers who keep throughput steady in production, not just in a demo.
2. Built for AI and LLM Workloads
FastAPI is the go-to framework for serving models and LLM features. Our developers come from a team that has shipped 150+ AI projects. They know how to stream responses, batch inference, and keep heavy compute off the request path.
3. Enterprise Integration Experience
Your API rarely lives alone. Our engineers connect FastAPI services to ERPs, CRMs, payment gateways, and legacy databases, with OAuth2, JWT, and audit logging built in from the first sprint.
4. Remote FastAPI Developers Who Work Your Hours
Hire a remote FastAPI developer who joins your standups, Slack, and Jira, with working hours that overlap the US business day. Entrans delivers from the US and India, so handoffs stay short.
5. Flexible Terms That Grow With You
Start with one engineer on contract-to-hire or project terms. When the roadmap grows, add QA, DevOps, or data engineers from the same bench of 500+ domain-trained professionals.
Hire FastAPI Developers From Entrans Who Are Certified and Experienced
Our FastAPI engineers own the whole API lifecycle. They design the contract, write the code, test it under load, and keep it healthy once it ships.
High-Throughput REST and GraphQL APIs
Our developers write async endpoints with Pydantic v2 models and use dependency injection for auth and sessions. Your client teams get OpenAPI docs they can generate code from. Where GraphQL fits better, they use Strawberry.
LLM and AI Model Serving
They build streaming chat endpoints, RAG pipelines with LangChain or LlamaIndex, and model APIs on OpenAI, AWS Bedrock, or your own models. Need AI agents that call your APIs? We pair this work with agentic AI framework integration.
Microservices and Event-Driven Systems
Small, focused services that talk through Kafka, RabbitMQ, or Redis streams. Long jobs move to Celery or a durable queue instead of in-process background tasks, so work survives a restart.
Async Database Layers
SQLAlchemy 2.0 async sessions, asyncpg, and Alembic migrations on PostgreSQL. Our engineers scope each session to one request and size pools to your worker count. That is where most production FastAPI bugs hide.
Migration and Performance Tuning
We move Flask or Django REST endpoints to FastAPI and upgrade Pydantic v1 code to v2. We also find the blocking calls that quietly kill concurrency. This work fits well with our application modernization services.
Deployment, Testing, and Observability
They tune Uvicorn and Gunicorn workers, build Docker images, and ship on Kubernetes. CI/CD runs pytest and Locust load tests on every build. Our DevOps and quality engineering team can add Prometheus and OpenTelemetry monitoring.

Our Customer Success Stories
Built an AI-Powered Invoice and GRN Reconciliation Platform
Industry: Finance and Procurement
Technical Stack: Python, Flask, AWS Bedrock (LLMs), PostgreSQL, MongoDB
A procurement-focused enterprise matched invoices, purchase orders, and goods receipt notes by hand. The documents arrived as PDFs, scans, and structured records. Our Python engineers built an AI platform that pulls key fields with LLMs on AWS Bedrock. It checks each invoice against PO and GRN data and flags price or quantity gaps for review. The result was an 80% cut in manual reconciliation effort and 2X faster payment processing.
Connected a Ticketing Platform to 100+ Global Sales Channels Through One API
Industry: Events and Entertainment
Technical Stack: Centralized API, real-time inventory sync, automated feed pipelines
A major ticketing platform had strong inventory but no simple way to reach buyers overseas. Every new partner meant another custom integration. We built a single API that takes standard inventory feeds and sends them to box offices, sports leagues, theater networks, and corporate booking programs. Ticket availability stays in sync across every channel in real time. Partners now reach 100+ sales channels through one integration, onboard new channels 2X faster, and carry 15% less unsold inventory.
Designed for Enterprise Speed and Control
Hiring a FastAPI developer through Entrans takes days, not months. You stay in control of who joins, how they work, and when the team grows.
1. Share Your Requirements
Tell us about your API, traffic, data stores, and any AI features on the roadmap. A 20-minute consult is usually enough.
2. Get Curated Profiles (Within 24-48 Hours)
Get profiles of FastAPI engineers who match your stack, seniority, and time zone. Each one shows relevant production work.
3. Evaluate and Interview
Run your own technical interview. Ask how they choose between async and sync routes, how they scope database sessions, and how they deploy on Kubernetes.
4. Onboard and Kickoff (Within 48-72 Hours)
Your developer gets repo access, joins your sprint rituals, and starts on real tickets in the first week.
5. Continuous Support and Scaling
We track delivery and fit with you. Add engineers, swap roles, or scale down as your roadmap shifts.
Our Hiring Models
Dedicated FastAPI Developers
Hire a dedicated FastAPI developer who works only on your product, full time, for the long run. Best for platforms where one engineer should own the API layer across releases.
Team Augmentation
Add FastAPI skills to the team you already have. Our engineers work next to your Python developers and follow your code review rules. When AI features land on the roadmap, they can pair with an LLM engineer.
Project-Based Engagement
Hand us a scoped deliverable, such as a new API service, a Flask to FastAPI migration, or a model-serving endpoint. We agree on milestones and acceptance criteria up front, including load test targets.
Industries Where Our FastAPI Developers Deliver Impact
Our team serves global clients in banking, healthcare, manufacturing, retail, and fast-growing startups. Our FastAPI specialists build secure, fast APIs. They bring deep skills in async Python, data platforms, and AI.

Book a Free ConsultationFrequently Asked Questions
What does a FastAPI developer do?
A FastAPI developer is a Python engineer who builds web APIs, microservices, and AI backends with FastAPI, an async framework built on Starlette and Pydantic. Day to day, they design data models, write async endpoints, connect databases and outside services, and publish API docs. Senior engineers also tune Uvicorn workers and write tests. Most of all, they keep blocking code off the event loop so the API stays fast under load.
How much does it cost to hire FastAPI developers?
The cost depends on seniority, location, and engagement model. Offshore and nearshore FastAPI developers commonly bill about $25 to $60 an hour, while senior US-based engineers often charge $100 an hour or more. Entrans shares a clear quote after a short scoping call, based on the seniority and hours your roadmap needs.
Should I hire a dedicated FastAPI developer or a freelancer?
Hire a dedicated FastAPI developer when the API is core to your product and needs steady ownership, security reviews, and long-term upkeep. Freelancers can suit small, well-scoped tasks with low risk. A dedicated engineer from Entrans also comes with vetting and backup from our QA, DevOps, and data teams.
When should I choose FastAPI over Django or Flask?
Choose FastAPI when you need APIs that handle many requests at once, typed data contracts, automatic OpenAPI docs, or an LLM backend. Django fits database-heavy web apps that need a built-in admin panel. Flask still works well for small synchronous services. Many teams run Django for the web layer and FastAPI for the API layer.
Is it safe to hire a remote FastAPI developer?
Yes, as long as the partner has the right controls in place. Entrans is ISO certified, signs an NDA before work begins, and assigns code and IP ownership to you. Our remote FastAPI developers work inside your repos and cloud accounts with scoped access, and their hours overlap the US business day for daily standups.
