What I built
Architecture
A typed TypeScript Redux Toolkit store, RTK Query for REST APIs with caching and auth flows, React Navigation and a library of reusable components.
Platform features
FCM push notifications, deep linking, AsyncStorage offline storage and Keychain-secured tokens for financial data.
Accessibility (my idea)
Proposed and built text zoom and voice-out so older savers could use the app. Both shipped.
Under the hood
Debugged Android native modules (Kotlin/WebView) during the React Native New Architecture migration.
Impact
- ~50%faster feature delivery from reusable components
- 35%fewer production defects, helped by Jest unit tests and better team testing practices
- 20%faster load time through lazy loading
- 40%reported gain in user satisfaction from the mobile-first migration I helped deliver
Leading people
Reporting manager for 2 associates for nearly 2 years: assigned work, reviewed their pull requests, set goals and shaped their salary-linked annual evaluations. I also interviewed candidates and presented progress to our UK clients.
