Building money tools families can trust.

These days I'm a software engineer at Cash App, working on Cash App Families. Lately that's meant Sprout — Cash App's managed accounts for kids 6 to 12 — where I lead Android and partner across server, iOS, and web to ship the account and safety systems end to end.

  • Technical leadership

    Leading Android for Sprout — managed accounts for kids 6 to 12 — and the broader Cash App Families account and safety systems.

  • Full-stack delivery

    Shipping features end to end across Android, server, iOS, web, and protos — the systems, not just the screens.

  • Raising the team

    Internal talks and AI-assisted developer tooling that other engineers actually adopt — making the whole team faster, not just me.

Point of View

02 — How I build
The best software feels like it was made by hand — fast, honest, and quietly considered down to the last detail.

01 Craft over noise

I sweat the small interactions — motion, timing, haptics, empty states. The stuff users don't notice until it's missing.

02 Developer experience

Good products come from happy teams. I invest in tooling, architecture, and DX so shipping stays fast and fun.

03 Always building

Side experiments, dApps, and tiny tools keep my hands dirty and my taste sharp. The web should be a place to tinker.
