Python FastAPI Development Company in India
Build lightning-fast APIs and AI backends with FastAPI. We develop async Python services with automatic documentation, Pydantic validation, and production-grade infrastructure. The framework behind modern AI/ML serving.
Proof-First Delivery
Measurable Outcomes We Optimize For
What We Offer
Service Modules Built for Production
Each module is designed as a production block with integration boundaries, governance hooks, and measurable outcomes.
FastAPI Application Development
REST and GraphQL APIs with automatic OpenAPI/Swagger documentation, Pydantic request/response validation, dependency injection, and async endpoint handling. Type-safe Python that generates its own docs.
AI/ML Model Serving
Serve machine learning models in production — LLM APIs, embedding endpoints, image classification, NLP pipelines. FastAPI handles concurrent inference requests with async I/O while keeping latency low.
Microservices & Event-Driven Systems
Lightweight FastAPI microservices with message queues (RabbitMQ, Kafka, Redis Streams), service-to-service communication, distributed tracing, and container orchestration with Docker and Kubernetes.
LangChain & LLM Backends
FastAPI backends powering LangChain applications — RAG pipelines, agent APIs, chain execution endpoints, streaming responses, and conversation memory management. The API layer for your AI stack.
Database & Infrastructure
PostgreSQL with SQLAlchemy/SQLModel, MongoDB with Motor, Redis caching, Celery/Dramatiq task queues, Alembic migrations, and connection pooling. Production database patterns for Python backends.
Testing & DevOps
Pytest test suites with async test support, integration testing, load testing with Locust, Docker containerization, CI/CD with GitHub Actions, and cloud deployment on AWS/GCP/Azure.
FastAPI-Native Team
We use FastAPI idiomatically — dependency injection, background tasks, middleware, WebSockets, and lifespan events. Not Django developers writing FastAPI like it is Django.
AI/ML Infrastructure Experience
We build the API layer for AI systems — model serving, RAG backends, agent APIs, and ML pipelines. Python for data science, FastAPI for production serving.
Async-First Architecture
Proper async/await patterns, connection pooling, non-blocking I/O, and concurrent request handling. FastAPI performance that actually delivers on its benchmarks.
Full-Stack Python + TypeScript
FastAPI backend paired with Next.js or React frontend. Auto-generated TypeScript clients from OpenAPI specs. End-to-end type safety across the stack.
