    Small interactive toys from this portfolio: Fourier epicycles, a themed crossword and a bot that walks where you click.

Cels

Method

How I work, sheet by sheet. Scroll to walk through them, or hover, focus or tap a cel.

Mindset

Curious, calm, always a beginner.

I take things apart to see how they work, and I am comfortable starting without every answer. Failures are data, error messages are a roadmap, and I never know everything, so I get good at finding out.

  • Curiosity
  • Resilience
  • Humility

Thinking

See the whole system.

I go back to first principles, then look at how the parts interact and what they set off second-hand. I trust measurements over habit, and I ask what happens off the happy path: ten clicks, a dropped connection.

  • First principles
  • Systems
  • Edge cases

Method

Constraints first, then trade-offs.

I pin down goals and limits before building, then balance cost, speed and quality, knowing there is no perfect answer. Big problems get cut into small modules, and every shortcut is debt I keep track of.

  • Requirements
  • Trade-offs
  • Modularity

Craft & Ecosystem

Ship small, automate, leave it better.

I prototype early, learn from real use, and chase the root cause rather than the symptom. I automate the repetitive, refactor before I commit, and write for the next person, who is often me, standing on the shoulders of open source.

  • Iterate
  • Automate
  • Empathy
