On the Practice

About — Services

I design and ship mobile and web products with React, React Native and TypeScript. I own the architecture, lead the team, and carry the product through to release on the App Store and Google Play — review edge cases included.

One specialty stands apart: white-label app families — one codebase, dozens of brands. More than four hundred apps have shipped through that model. I have worked with teams in the US, New Zealand, Australia, China and Russia — remote and async.

Apps shipped 400+ Teams up to 7 people Hours UTC+10

KAR — five apps on one codebase

The largest dance competition network in the US. I reworked a legacy app into a “skeleton + skin” architecture: a shared core with per-brand theming and configuration. Real-time results, live streams, iPhone Live Activities.

Macroactive — 400+ apps shipped

A platform for fitness trainers and online coaches with millions of MAU. I replaced a monorepo of a hundred branches with a modular “skeleton + skin” system and a semi-automated build pipeline. Release time dropped from days to two hours.
