Front-end technical leader whose career grew from software quality and automation into React platform ownership.

The number 4 in Worldsaic lights, a Math Bearings exercise, and a recipe.

Math
Bearings

mathbearings.com

Math practice that grades the learner’s method and revisits skills over time.

A deterministic core handles curriculum, scheduling, and grading, with storage and rendering kept separate.

  • Pure domain core, platforms at the edges
  • Grades the method, not the answer
  • Hints that cannot reveal the result
  • Mastery decays until re-demonstrated
  • Learner records never leave the device
  • Offline and privacy proven by tests

Shared-world art game · Live

Worldsaic

A relaxing art game where Earth becomes a shared canvas. Draw with light, connect with neighboring creations, and follow real rivers from a glowing globe down to a single tile.

Built with a custom Canvas 2D renderer, spatial sound, and a persistent shared world. Drawings stay in local drafts until the player publishes them.

  • Continuous exploration from globe to tile
  • A 24 × 24 canvas for drawing with light
  • Connected creations and real river journeys
  • React, TypeScript, Canvas 2D, and Web Audio
  • Shared persistence with atomic tile releases
  • Keyboard, touch, and reduced-motion support

Engineering Focus

Front-End Platforms

Shared architecture, ownership boundaries, and standards that help teams move without drifting apart.

  • TypeScript
  • React
  • Architecture
  • Accessibility
  • Performance

Models in Production

I focus on what happens after the demo: identity, cost, failure handling, and user trust.

  • LLM APIs
  • Vision
  • OCR
  • Usage controls

Quality & Delivery

I use automation to shorten feedback without replacing engineering judgment.

  • Test strategy
  • CI/CD
  • Mentoring
  • Developer tooling

Cross-Team & Product

Most of the work is agreement: what we build, who owns it, and when it ships.

  • Stakeholder alignment
  • Technical direction
  • Multi-product delivery
  • Mentoring

Get in Touch

If you are working through front-end platform ownership, reliable delivery, or where models belong in a product, I would like to hear what you are building.
