• Implemented JWT authentication and role-based authorization for secure access control.

• Designed RESTful APIs for product, cart, customer, and order management.

• Used PostgreSQL for reliable relational data storage and optimized database operations.

• Integrated Redis for caching to improve API performance and reduce database load.
