hi, santosh here.
been here for years
I'm a software engineer and computer science student from Coimbatore. I enjoy building useful products, especially where dependable backend systems and applied AI meet.
01 / About
I like learning by building the whole thing.
I started by hacking around on the internet and kept following the questions deeper: how data moves, where systems fail, and what makes software feel trustworthy. I now build end-to-end products with a particular interest in backend engineering, real-time systems, and useful AI.
I'm graduating in May 2026 and looking for a team where I can learn quickly, own meaningful work, and keep raising the quality of what I ship.
Tech I work with
- TypeScript
- Next.js
