About Me

I am a 24 year old systems programmer who loves low-level tinkering, breaking things, and re-inventing the wheel. I started pursuing a PhD in computer science at UC Santa Cruz in late 2016, and my current research is regarding non-volatile memory support in operating systems. In the past I have developed a self-hosting Unix-like kernel and userspace to learn about kernel engineering.
