What I'm looking for

I’m looking for a remote-friendly role where I can own mobile features end-to-end, make technical decisions on scalable React Native/Android architecture, and collaborate with product, backend, and design teams to deliver high-performance experiences in fast-paced environments.

I’m a Senior Mobile Engineer with 7+ years of experience building scalable React Native and Android applications used by millions of users across fintech and consumer platforms. I translate complex product requirements into maintainable mobile systems through cross-platform architecture, native Android integrations, and performance-focused engineering.

At Intuit, I lead development of high-performance React Native solutions, architecting large-scale mobile features and building reusable infrastructure to improve cross-platform efficiency. Across Chime, Charlie Finance Co., and earlier work at Google, I’ve integrated REST/GraphQL APIs, implemented real-time and offline-first experiences, improved rendering and async data flows, and supported reliable releases with CI/CD and monitoring—often mentoring engineers and driving end-to-end feature delivery.
