About

I've been into computers since I was 7. I got into programming during secondary school, quickly moved to Linux, and built my first PHP website. Ever since migrating to Linux I've been an open-source advocate.

In my free time I study Japanese (reached JLPT N4) and I am doing historical fencing. I enjoy reading books on economics, politics, management, and software development. Occasionally I work on one-off side projects involving programming and data processing.
