Hi 👋, I’m Varun, a Senior Software Engineer at Renault Nissan Technology and Business Center India (RNTBCI). I build full-stack applications that bring AI-powered insights to supplier risk assessment, procurement, and sustainability—helping businesses cut through paperwork and make better, data-driven decisions.
My core stack is Next.js, React, and Tailwind CSS on the frontend, and NestJS, Postgres, and Java on the backend. I also have hands-on experience with Node.js, Express, MongoDB, and MSSQL, giving me a strong foundation in both SQL and NoSQL systems. I’m passionate about scalable architecture, clean code, and continuous learning.
Currently, I’m sharpening my skills in Java, MCP servers, and vibe coding, while planning to explore Go, Rust, and C to get closer to the low-level systems that fascinate me.
