System Overview

Full-stack ecommerce platform with a microservices-based architecture.

Built as an end-to-end e-commerce ecosystem featuring JWT authentication, decoupled multi-gateway payment processing via Payment Orchestration Engine, performance-optimized Redis caching, and asynchronous email notification workers powered by BullMQ.

Key Architectural Highlights

• Built a full-stack ecommerce platform with JWT authentication, product catalog, cart, order management, and inventory tracking.
• Optimized platform performance using Redis caching, implemented rate limiting and request validation to prevent abuse, and built a real-time analytics dashboard.
• Decoupled payment processing by integrating Payment Orchestration Engine microservice, enabling secure multi-gateway payments (Razorpay, Cashfree) with webhook verification and idempotent payment handling.
• Built asynchronous email notification system using BullMQ job queue, ensuring reliable order updates and decoupling email delivery from request lifecycle.
