Web engineer · Product builder

I engineer the web for golfers, dog people, trivia fans, plant nerds, and biohackers.

From charity golf platforms behind tens of thousands of tournaments to baseball trivia, field guides, and creative tools, I design, build, and ship products that people come back to.

02 — Approach

How I build. Small team energy, production-grade results.

Product first

I start with the person on the other side of the screen, whether that’s a tournament organizer on deadline or a fan with five minutes to kill. Then I engineer backward from there.

Fast is a feature

Lean pages, sensible caching, and images that earn their bytes. Speed shows up in conversion rates, search rankings, and how the product feels.

Interfaces with personality

A pitch clock on a trivia game. A seed spiral as a search index. Small, memorable details are what make a product someone’s favorite.

Built to be found

Structured content, clean semantics, and information architecture that scales from ten pages to thousands without losing its shape.
