I'm a pragmatic web developer and software engineer who is passionate about the web, frontend technologies, and the open source ecosystem.
A Short Introduction
I've been programming since I was 12 years old. What I have learned so far can be summarized as "the less code the better".
However, we live in the real world, so I have learned to cope with gigantic codebases and have gotten used to spending hours debugging through strange code written before I even graduated from high school.
In my spare time, I enjoy making and listening to music, playing old video games, and working on my own side‑projects. I'd love to show you all my music but no one ever seems to ask...
