What I'm looking for

I'm looking to build scalable mobile and web products where I can own end-to-end features, improve performance and reliability, and contribute to product growth in a fast-paced startup environment.

I've delivered production-ready React Native features for Zeller Australia, using GraphQL and Apollo Client for efficient data fetching, React Native Reanimated for responsive interactions, and Jest tests reaching up to 90% coverage for new modules. I also use Claude Code and GitHub Copilot to accelerate development, refactoring, debugging, and reusable task automation.

At CashBook App, I reduced JavaScript thread block time by 40%, built UPI flows, enabled Google and Apple sign-in, and managed releases to Google Play and the Apple App Store. Earlier at Unthinkable Solutions, I built cross-platform apps across fintech, healthcare, and media streaming, including OpenTok video calling, SQLite offline support, Detox automation, and CI/CD pipelines.
