What I'm looking for

I’m looking for a Full-Stack role where I can own backend architecture with Node.js/NestJS, build secure scalable REST APIs and event-driven microservices on AWS, and ship real-time React dashboards with production-quality, well-tested code.

I’m a Full-Stack Developer specialized in Node.js, NestJS, and React, with a strong focus on backend architecture. I design and deploy scalable REST APIs, secure authentication systems using JWT and refresh tokens, and event-driven architectures with AWS SQS. I deliver complete features from backend to frontend with clean, well-tested code running in production using Docker, GitHub Actions, and AWS.

In my projects, I built a complete AuthService that uses short-lived JWTs plus rotating refresh tokens persisted in PostgreSQL, with Redis-based revoked token blacklisting and IP-based rate limiting. I also architected microservices for e-commerce with async SQS workflows, created real-time business metrics dashboards with WebSockets, and developed an API Gateway with per-route/per-client rate limiting, correlation IDs, and circuit-breaker observability.

Work history, roles, and key accomplishments

API Gateway & Observability

Personal Project

Jan 2024 - Present (2 years 3 months)

Developed a lightweight Node.js/NestJS API Gateway with Redis-based sliding-window rate limiting per route and user tier, plus structured request logging with correlation IDs for end-to-end traceability in CloudWatch logs. Added downstream health checks with a circuit breaker (503 after 3 consecutive failures) and published OpenAPI/Swagger documentation alongside a Postman collection with examples

Real-Time Metrics Dashboard

Personal Project

Jan 2024 - Present (2 years 3 months)

Built a NestJS backend with Socket.io WebSockets to emit real-time tenant metrics updates to React clients subscribed by room. Implemented JWT-authenticated WebSocket handshakes, Redis pub/sub propagation across instances, and a PostgreSQL data model with date-based partitioning, deployed on AWS EC2 with Nginx WebSocket reverse proxy and a custom-domain Next.js frontend.

Auth Service (NestJS)

Personal Project

Jan 2024 - Present (2 years 3 months)

Designed a NestJS authentication service using short-lived 15-minute JWTs and rotating refresh tokens stored in PostgreSQL, eliminating invalid sessions after token theft. Implemented a Redis-backed revoked-token blacklist with dynamic TTL and sliding-window rate limiting (max 5 attempts/15 min), and deployed on AWS EC2 with Docker, GitHub Actions CI/CD, and Swagger documentation.

E-commerce Microservices

Personal Project

Jan 2024 - Present (2 years 3 months)

Architected three NestJS microservices (users, products, payments) behind AWS API Gateway/ECS, using SQS for decoupled order-flow processing with configurable retries and a dead-letter queue. Added Redis caching for the product catalog with event-driven invalidation and automated Dockerized builds/deployments to ECS via GitHub Actions.
