How I work

  • Ship first, then polish. You see a working build early, not a slide deck.
  • Grounded AI. I design features so the model's output can be checked, logged and explained.
  • Motion with a job. Animation has to guide attention or explain something, or it doesn't go in.
  • Green builds. My main projects build and test in GitHub Actions on every push.
  • Clean handover. Deployed app, readable source, a README like the ones above, and a short walkthrough.

Let's build something people remember. Message me on Contra.
