About

Senior iOS & React UI/UX Lead with 10+ years building secure, high‑scale mobile products across banking and consumer apps. I specialize in Swift, SwiftUI, UIKit, and React Native, shipping pixel-perfect mobile experiences used by millions of users. At DBS Bank, I architected a React component library adopted across 5 domains, improved app startup and runtime performance, optimised memory usage, and mentored a team of iOS engineers while maintaining a 99.9% crash‑free rate in production. Previously at foodpanda (Delivery Hero), I led iOS development for an app serving 5M+ users across APAC, delivering real‑time order tracking and a modular MVVM architecture with strong automated test coverage and fast, reliable releases. I enjoy working end‑to‑end with backend teams and apply AI to accelerate delivery, from LLM‑powered dashboards to fraud‑call detection MVPs and mobile security tooling. I’m open to Senior / Lead iOS roles in fintech, e‑commerce, or consumer tech (Singapore, India, or remote).
