About me

I'm a self-taught full-stack developer with a background in audio and electronics engineering. My work focuses on Python development for data acquisition, data visualization, and UI/UX design.


Outside of work, I enjoy playing guitar, repairing and creating, and working on hardware and software projects. Most of my projects are open-source, and you can learn more about them here.


Technically, I'm passionate about mechanical keyboards, guitar tech, PCB design, MSLA 3D printing, web and game development, and graphic design. Beyond tech, I love Dungeons & Dragons, astronomy and astrophysics, craft beer, pixel art, linguistics, cooking, science fiction, and video games.

Projects

Almost every project starts as an excuse to learn something new or practice something I've learned. I've written a few extensions for the Aseprite pixel art editor, all of which are available on my itch.io page for free / "pay what you want". If you find them useful, please consider donating to support future development! I also work on hardware projects, including custom mechanical keyboards, guitar effects pedals, and more. I develop apps and CircuitPython libraries to solve specific problems and enhance my workflow.

Sluggify Lua

Sluggify Lua is a Lua port of skeddles/sluggify that converts strings into URL-friendly slugs. I originally wrote it as a part of Lospec Palette Importer, but I thought it might be useful on its own. You can use it to create clean and readable URLs from arbitrary text.
