Project Title: Secure E-Commerce Backend (Spring Boot, Redis & JWT)
I designed and developed a secure, production-ready e-commerce backend utilizing a clean layered architecture and RESTful principles. Built to handle complex business logic, this project handles everything from user lifecycle management and strict authentication to secure transaction processing and high-speed data retrieval.
Key Engineering Highlights:
Modular Architecture: Engineered 40+ secure CRUD endpoints spanning 6+ core modules: User, Product, Category, Order, and Auth, Wishlist
Advanced Security & RBAC: Implemented Spring Security with custom JWT filters, BCrypt password hashing, and granular Role-Based Access Control enforcing 3 distinct tiers (ADMIN, USER, SELLER).
Transaction Atomicity: Built robust transaction management to guarantee atomicity and data consistency across order placement and cancellation workflows.
Database & Caching Optimization: Optimized MySQL schemas via complex JPA relationships (@OneToMany, @ManyToOne) and Hibernate custom queries. Integrated a Redis caching layer that slashed product retrieval latency by 88.87% (from 3.37 s down to 375 ms).
Containerization: Fully containerized the application stack using Docker Compose for seamless, reproducible local and cloud deployments.
