About

A bit about me

I'm Gokul Janarthanan — a Full Stack Engineer based in India who thrives at the intersection of design and engineering. Frontend is where I come alive, but I'm equally comfortable building APIs, managing databases, and shipping products end-to-end.

Over the past 4+ years, I've built and shipped production apps across startups and clients — React, Next.js, Node.js, MongoDB, PostgreSQL, and cloud platforms. I care about the details: smooth interactions, clean architecture, systems that scale, and deploys that don't break at 2 AM.

Outside work, I build side projects that automate tedious things — like this very app, which sends AI-written follow-up emails so you never miss a job opportunity again.
