About
Viju Sanjai

A little about me.

I'm Viju Sanjai, a B.Tech student in Electronics and Communication at VIT Chennai, building at the intersection of systems programming and full-stack development. I care about writing software that's fast, correct, and deliberately crafted — whether that's a GPU video pipeline or a browser-native PDF editor.

Previously a software development intern at Lagoon Technologies, working on enterprise tooling in C# and .NET. Outside of work I research quantum-chaotic steganography, mentor students on Git and open-source practices, and dig into low-level challenges through CTFs.
