What I'm looking for

I’m looking for a role where I can build secure backend APIs and ship AI features—like LLM/RAG experiences and agent workflows—working across Node.js/React and getting projects to production-ready quality.

I built backend APIs for a Learning Management System (LMS) using Node.js, Express.js, and MySQL, including JWT authentication and RBAC to secure user and admin endpoints.

I also worked on full-stack MERN projects like RoomBalance—adding expense tracking, chore allocation, and a dynamic fairness scoring system—and tied in JWT/OAuth authentication plus dashboarding and automation.

On the AI side, I created an ATS resume analyzer with LLM-driven feedback and built a production-ready AI agent with LangGraph, RAG, tool routing, and human-in-the-loop approval.
