Freelance SQLAlchemy, Alembic & Asyncpg Programmer: High-Concurrency Async Python Databases
Modern asynchronous Python backends built with FastAPI and Ariadne/Strawberry GraphQL only achieve true non-blocking concurrency when paired with SQLAlchemy 2.0 AsyncSession, `asyncpg` binary protocol drivers, and disciplined Alembic schema migrations.
As a Senior Freelance Python & Database Programmer, I architect high-throughput async data layers and isolated Pytest transaction test suites. Hire Aldian Fazrihady on Upwork (aldianf).
