E-Commerce Backend API

May 5, 2026 – Present

Engineered a REST API with JWT-based authentication and a normalized PostgreSQL schema covering users, products, orders, and inventory. Eliminated N+1 query issues using prefetch_related and the Prefetch class, reducing database execution time by 40% for complex order lookups. Implemented atomic transactions with select_for_update() and F() expressions to ensure race-condition-free stock management during concurrent checkouts. Integrated a Redis caching layer to store frequently accessed product listings, significantly reducing API response latency under load. Containerized the full application stack using Docker and Docker Compose, enabling consistent cross-environment deployment with a single command. Applied the service layer pattern - keeping serializers responsible for validation, services for business logic, and views as thin HTTP adapters for maintainable architecture.

Multi-Tenant E-Commerce SaaS API

May 5, 2026 – Present

Architected a multi-tenant SaaS platform using django-tenants with PostgreSQL schema-level isolation, ensuring zero data leakage between merchant tenants. Designed a custom AbstractUser model with Role-Based Access Control (RBAC), supporting distinct permission sets for platform admins, merchants, and customers. Implemented an async task queue using Celery and Redis for background jobs such as order confirmation emails and inventory sync, decoupling them from the request cycle. Optimized platform-wide product discovery by integrating Elasticsearch for full-text fuzzy search across multi-tenant catalogs. Built comprehensive API documentation using Swagger/ReDoc with API versioning for clean third-party developer integration.
