Message

At SmartData Enterprises, I built and maintained cross-platform mobile applications with React Native and TypeScript, including TrackTreads, an enterprise inspection app with real-time and offline syncing.

I designed a GraphQL data layer with Apollo Client that reduced over-fetching and improved API efficiency by 30%. I also optimized list rendering, improving large-dataset rendering speed by 40%.

At Solitaire Infosys, I developed reusable React Native component libraries and contributed to an on-demand delivery ecosystem with customer- and merchant-facing apps. I also led client walkthroughs and requirements-gathering sessions.
