Hi..

I work as an R&D engineer in telecom, mostly around DWDM systems, monitoring, and control-plane software. A lot of my work involves building and fixing things at the system level—usually in C/C++—and making sure they actually hold up in real conditions.

I’ve worked on spectrum sharing and performance monitoring, where I’ve had to deal with everything from low-level device integration to system-wide behavior. I like going deep into problems, especially when they’re messy and don’t have obvious answers.

Outside of that, I build small system tools and simple web stuff. I prefer things that are minimal, practical, and easy to understand—nothing overengineered.

Coming soon..
