About this site (2026 edition)


In this current age of tech,

  • When artificial intelligence is given more value than human intelligence...
  • When oligarch CEOs wield power over our government and institutions...
  • When Silicon Valley profits from surveillance, misinformation, and genocide...

As a designer, developer, and tech worker, I've been grappling with questions:

What is my place in all this? What do I do when empathy, diversity, equity — values I hold dear — are no longer welcome? What does it mean to build software at the whim of a growth-at-all-costs investor class? How do I talk about my work and express myself when I no longer recognize the industry I built a career in?

This version of my website is my attempt to answer these questions. Aside from being a freelance portfolio, this site also serves as my digital garden — a collection of imperfect notes and ideas to expand on slowly over time.

It’s a place where I can not only reflect on my work, but also exercise my rights to free speech and self-expression, which are critical to a democracy. And who knows, maybe it can be a place to connect with others who feel the same way...

Thank you for visiting, and stay safe.

– Matt
