Hi there, I'm

Brandon Mathis

It's nice to meet you.

For me software is also a hobby and I love a good side project to keep me sharp. Here are a handful of projects I've created for the simple joy of building things.

Color Picker

  • React
  • Typescript
  • CSS
  • Vite
  • Vitest

I started this project in 2011 to learn about different color spaces and experiment with HSL which was new to the web at the time. Today it's a modern React/TypeScript app that features wide gamut support through OKLCH (accessing vibrant P3 colors impossible in sRGB) including a real-time visualization of gamut boundaries, and live updates across all color models to help users understand how different color spaces relate. With around 40k unique visitors monthly, it's become a go-to tool for designers and developers exploring modern CSS color capabilities.


Court Shuffle

  • React
  • Typescript
  • Tailwind
  • Vite
  • Convex
  • Zustand

I wrote this app to help tennis and pickleball players easily organize casual play. Select court numbers and let everyone draw a card. The number matches the court and the suit helps players find a parnter or opponent. I built this app as a PWA so users can install it on their homescreen for offline use. For those with a data connection, they can share the deck and draw from multiple devices and it's all synced instantly with a Convex backend.


Octopress

  • Jekyll
  • Ruby
  • Javascript
  • HTML
  • CSS

During the great indie blogging bubble, I built Octopress, a powerful companion to the Jekyll blogging engine, designed to give developers a beautiful way to blog. With over 2.5k forks and more than 9k stars on GitHub, it remains my most widely known project. More than just a Jekyll theme, it included a robust code-highlighting system, social feeds (when those were prevalent), and a suite of powerful shell scripts to automate managing drafts, publishing, and even a hooks framework to prioritize plugin patches.
