About Me

I'm a Full Stack Developer who builds production-grade web applications and automated backend systems. I work across the stack — React.js and Next.js on the frontend, Node.js, Django, and FastAPI on the backend — with PostgreSQL, MongoDB, and Redis powering the data layer. I engineer CI/CD pipelines with Jenkins, manage AWS infrastructure, and integrate services like the Meta WhatsApp Business API and Razorpay. From freelance client deliveries to enterprise deployments, I focus on shipping reliable, scalable software.
