Backend / FastAPI / PostgreSQL
Python API Development
FastAPI + PostgreSQL backend with optimized queries and CI/CD.
Problem
Design a reliable backend system with clean API design and optimized data access.
Approach
Built a multi-tier FastAPI service with SQLAlchemy models, schema validation, and RESTful routing. Added indexing and ORM-level caching to improve query performance and wired GitHub Actions for CI/CD with pytest automation.
Results
- 15% faster data retrieval via optimized queries
- Modular, testable API design
