What I'm looking for

I want to build and optimise production mobile apps in Agile/Scrum teams—leading architecture and mentoring others—while delivering secure, scalable features with measurable performance gains, smooth OTA/CICD releases, and clean, maintainable code.

I’m a Senior React Native Developer with 7+ years of end-to-end mobile development experience, delivering cross-platform Android & iOS applications to 500K+ end users across fintech, e-commerce, streaming, and social platforms. I focus on performance optimisation and scalable architecture, including FlashList migrations, CodePush OTA deployments, and cold-start reduction.

I’ve led small engineering teams through architecture decisions and code reviews, and I’ve built secure, offline-first workflows for mission-critical onboarding experiences. From Redux Toolkit/RTK Query state management to CI/CD with GitHub Actions and App Store/Play Store submissions, I consistently ship production-ready features in Agile/Scrum sprints.
