I’m a Full-Stack Software Developer with 1+ year of experience building production-grade web applications, REST APIs, microservices, real-time systems, and AI-powered backend workflows. I focus on scalable backend architecture, secure APIs, database optimization, and maintainable frontend workflows.

In my current role, I developed core backend and frontend modules for a production OTT streaming platform with subscription-based access and role-based workflows. I built scalable NestJS backend services using Prisma ORM with AWS RDS PostgreSQL, and engineered video analytics for watch progress and rule-based triggers.

I also implemented HLS/M3U8 adaptive video streaming using AWS S3 and CloudFront CDN, and integrated Redis caching with Redis Pub/Sub plus query optimization across AWS infrastructure. Earlier, I built responsive React.js component libraries and real-time supply chain dashboards, and I developed modular rental-platform UI flows with improved frontend maintainability.

My projects include a NestJS monorepo for gym management microservices and a LangGraph-based AI fitness agent with RAG-based workout planning and semantic search using pgvector. I consistently apply reliability and security patterns (circuit breakers, rate limiting, Helmet, JWT, RBAC), along with Swagger/OpenAPI and CI/CD practices.
