About Me

Building systems where correctness matters

I'm a Systems & Infrastructure Engineer with a strong focus on operating systems, embedded systems, and low-level infrastructure software.

My work sits at the intersection of software, hardware, and performance-critical systems, where correctness, reliability, and resource constraints matter more than abstractions. I'm currently pursuing BTech + MTech and contributing to production-grade open-source systems through Google Summer of Code.

🧠

Philosophy

Depth over breadth. Constraints drive good design. Measure, don't assume. Build → debug → document.
