About

Curious, collaborative, and relentless about the details.

I'm a product-focused engineer who cares as much about how a team works as what it ships. I start with the user and the problem before the solution, do my best work alongside product, design and engineering all pulling in the same direction, and embrace the hard problems most people skip. I stay curious, always experimenting with new tools and approaches, and I try to leave things better than I found them, for the next engineer as much as the user.

  • Product mindset

    I think in products, not tickets

  • Teamwork

    I get design and engineering speaking one language

  • Determination

    I push past 'good enough' on the problems others skip

  • Creativity

    Always experimenting with new tools and ideas

Say hello

Let's build something together.

Open to frontend web, hybrid mobile, Android and full-stack roles, freelance, and the odd side quest.
