about

Hey, that's me.

I'm a student from Sri Lanka who's really into figuring out how things work — not just using them, but actually understanding what's going on underneath. Big FOSS person. Linux is my daily driver and I genuinely care about open software and knowing what's running on my machine.

Most of my time goes into Linux, IoT, robotics, networking, and cloud infrastructure. I like the layer where software meets hardware — embedded stuff, networked devices, systems that do real things. I'm also slowly picking up offensive security on the side, mostly because understanding how things break is the best way to understand them at all.

Outside of tech, I'm into commercial aviation — the kind of avgeek who reads about airline ops, aircraft types, and how the whole global system actually holds together.
