Full-stack developer with 2+ years in the industry. I build things end-to-end — from database to deployment — and write about what I learn along the way. When the laptop closes, I'm usually chasing a trail somewhere.

I'm a full-stack developer based in Bengaluru with 2+ years of professional experience building web applications end-to-end. Before tech, I spent three years as a site engineer managing large-scale infrastructure projects — which taught me more about systems thinking, execution under pressure, and seeing things through than any bootcamp could.

This blog is where I document the build process: things I ship, problems I debug, tools I discover. The TIL section captures the small daily learnings that are too short for a full post but worth writing down before they fade.

What I work with

My day-to-day is JavaScript across the full stack — Node.js and Express on the backend, React on the frontend, MySQL and MongoDB for data depending on what the problem calls for. I've worked with Redis for caching, Qdrant for vector search, Socket.IO for real-time features, and OAuth 2.0 for auth. On the infrastructure side I'm comfortable with Linux, Nginx, Jenkins, and GitHub Actions — I've set up CI/CD pipelines, configured reverse proxies, and wired up Prometheus and Grafana for monitoring in production.

What I've shipped

Most of my professional work has been at QuGates Technologies in Bangalore — building ERP systems, an OAuth 2.0 SSO layer across internal tools, and a technical assessment platform that handled 10,000+ candidate sessions. One of the more satisfying wins was taking a MySQL query from a 6-second response time down to under 100ms through schema redesign and indexing. I've also contributed to Team Shiksha's open-source project, building React components and improving test reliability.

Outside the code

Bengaluru is a great base for anyone who likes the outdoors — Yercaud, Coorg, Chikmagalur, and the Western Ghats are all within reach on a weekend. I try to disappear into them as often as work allows. When I'm not on a trail, I'm likely out with the Robinhood Army — I've been an active volunteer for the past three years, helping distribute food to those who need it most across the city. Code or trail or community, it's all about showing up.
