04 / BEHIND THE BUILD

A developer’s mind.
A builder’s drive.

I’m Satyajeet, a backend and full-stack developer. I build personal products and reusable packages around problems I want to understand deeply.

My interests span real-time communication, Node.js, React, PostgreSQL, augmented reality, and media systems. I care about work that feels clear to use and remains clear to maintain.
