I ship products that engage

Products I've taken from an idea to live users, close reads of products I admire, and the decade behind it all.

How I work

four habits
  • Find the riskiest assumptions first. Discovery with the domain experts before building the spec. The thing most likely to kill the plan gets tested before the thing easiest to build.
  • Prototype, don’t just spec. Working prototypes engineers build from directly
  • Evidence before engine. Evals, ground truth, human review, threshold gating
  • Say no. Having the product judgement to know what to cut, ROI vs effort modelling, and the safety to protect it
  • Measure what matters. Stickiness and adoption, not velocity

Toolkit

  • Figma
  • PostHog
