What I'm looking for

I'm looking to build production-grade backend systems and end-to-end products, ideally in teams where I can work across APIs, databases, cloud deployment, AI integrations, and scalable customer-facing workflows.

I'm building Lead AI at Quan Technologies, an AI-powered CRM and marketing automation platform for India's real estate market. I own backend services supporting lead management, campaign automation, property inquiries, and sales workflows.

I use Node.js, Express.js, PostgreSQL, MongoDB, Redis, Firebase, AWS S3, and Prisma to deliver scalable services. I've integrated Apollo API, Google Gemini AI, WhatsApp Business API, Razorpay, RBAC, and production infrastructure on Linux VPS with Nginx.

At Tata Consultancy Services, I contributed to enterprise full-stack delivery in Agile teams, developing Angular components and Spring Boot REST APIs. I also maintained Java applications using JDBC, JSP, and Servlets while collaborating with QA, BA, and DevOps teams.

As the sole backend developer for Scrap Sevak, I delivered 15+ REST APIs for pickup scheduling, carts, payments, and user management. I also build blockchain projects, including a MERN auction platform with Solidity smart contracts and MetaMask authentication.
