An AI-assisted medical-diagnostics platform needed solid backend services and a reliable data layer to support its product, in a domain where data correctness and traceability are non-negotiable.
I designed and maintained the backend services with FastAPI, implemented the data-access layer with PostgreSQL and SQLAlchemy, and built the auxiliary microservices the system needed to run in a decoupled way.
A stable, maintainable backend supporting the product in production.
