Customer Platform — Backend API
Built a containerized customer management API using Python, FastAPI, and PostgreSQL 16. The platform provides reliable customer creation and data management through RESTful endpoints, with idempotency handling to prevent duplicate operations when requests are repeated.
Key engineering contributions:
Developed customer API endpoints using FastAPI and Uvicorn.
Integrated PostgreSQL 16 for persistent customer data storage.
Containerized the application and database using Docker.
Implemented idempotency-key handling to ensure repeated requests return consistent results.
Added request validation and error handling for missing idempotency keys and duplicate email addresses.
Configured and tested the application and database as connected services.
Technology: Python, FastAPI, PostgreSQL 16, Docker, Uvicorn.
Outcome: Delivered a reliable, containerized backend foundation demonstrating API design, database integration, request validation, and production-style service management.
