Projects
šļø E-Commerce Backend API
Stack: Node.js, Express, MongoDB, Redis, Cloudinary , Zod, Docker, Swagger
A scalable and production-grade backend designed for e-commerce applications. Implemented role-based architecture, token rotation, and IP-based rate limiting to ensure secure and efficient access control. Reused the authentication API for token management to simplify reusability and maintainability across different modules.
Integrated cart management using Redis for high-performance caching and session persistence, ensuring minimal latency for real-time cart updates. Added API documentation with Swagger for smooth developer onboarding and testing. Includes Zod-based schema validation, Dockerized container setup, and environment-specific configurations for scalability.
Focus: Security ā¢ Scalability ā¢ Reusability ā¢ Clean Architecture
š¦ Distributed Rate Limiter
Stack: TypeScript, Node.js, Express, Redis, Lua, Docker, Zod
Built a production-grade distributed rate limiter supporting Leaky Bucket, Fixed Window, Sliding Window, and Token Bucket algorithms, using Lua scripts for atomic Redis operations to ensure correctness under concurrent access.
Deployed a horizontally scalable Redis cluster with 3 masters and 3 replicas, ensuring race-free consistency and fault tolerance under sustained peak traffic.
Focus: Concurrency ā¢ Scalability ā¢ Fault Tolerance ā¢ Backend Systems
š Authentication API
Stack: Node.js, Express, Postgres, Redis, Nodemailer, Zod, Docker
Secure, production-ready authentication system built with modular APIs for login, signup, and token refresh. Implemented token rotation, IP-based rate limiting, and Redis-based session management to prevent token misuse and enhance scalability.
Added email verification and password reset flows using Nodemailer with JWT links. Fully Dockerized for easy deployment and consistent environment setup across systems.
