I'm a pragmatic web developer and software engineer. I'm 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...

- "Password Passthrough" Wordpress plugin - I made this Wordpress plugin for a company I worked at since they needed this very specific feature. However, I thought it could be useful to other people so I put it on the Wordpress plugin repository. Now it has over 100 active installs.
I have built a few CRUD apps at work, school, and also a few command-line programs that I've incorporated into my daily workflow. If you take a look at my Github, you'll notice there are a lot of oddball projects that I've stopped working on. This is usually because I try to come up with silly projects in order to learn a new programming language or framework.
The projects below are projects I built on my own in my spare time. They are not your typical software application, but more like something I enjoyed programming purely for fun.
