I've built backend platforms for Hexaloop Technologies, including scalable Node.js and Express.js microservices, RabbitMQ and BullMQ job processing, Redis caching, secure RBAC and JWT APIs, and optimized MongoDB performance.

Across IT Spark Technology and Fincooper Tech India, I developed RESTful APIs, integrated payment and financial-service APIs, automated AWS CI/CD deployments, and contributed to microservices migrations. I also containerized services with Docker and supported Kubernetes, AWS ECS, Lambda, and S3 deployments.

My project work spans salon booking, luxury chauffeur booking, travel, healthcare, and advertising platforms, with a focus on secure transactions, real-time availability, role-based access, database optimization, and production-ready systems.
