Building Reliable Software for Regulated, High-Stakes Environments.

I'm an iOS and backend engineer with 13+ years of experience delivering consumer and enterprise mobile software across banking, fintech, telecom and healthcare. My focus areas are Swift/SwiftUI development, secure authentication, and integrating mobile platforms with core banking and payment systems.

At OCBC Bank, I've led the modernization of legacy codebases, improved app performance by 40%, replaced SMS OTP with biometric authentication for a smoother and more secure login experience, and delivered DuitNow QR payments for business banking customers. I work closely with product, design and backend teams to ship features that meet strict security and compliance requirements without compromising on user experience.
