Freelance FastAPI & Pydantic Programmer: High-Throughput Async Python APIs & OpenAPI Schemas
FastAPI and Pydantic v2 have become the gold standard for building high-concurrency asynchronous Python microservices, AI agent backends, and webhook ingestion gateways.
As a Senior Freelance FastAPI & Python Programmer, I architect clean, dependency-injected FastAPI services backed by SQLAlchemy + asyncpg, Kafka/NATS event loops, and multi-stage Docker deployments. Hire Aldian Fazrihady on Upwork (aldianf).
