About

I am a Senior iOS Engineer & Technical Lead with over 7 years of experience building high-performance, scalable iOS applications using Swift and advanced architectural patterns like MVC, MVVM, VIP, and VIPER. I have led cross-functional teams to deliver secure, enterprise-grade apps in the banking domain, including the UOB TMRW app serving retail and private banking customers across Asia.

My expertise spans RESTful API integration, end-to-end encryption, unit and UI test automation (including Applitools-based visual testing), and driving CI/CD pipelines, resulting in a 40% improvement in app load time and 30% increase in user retention. I consistently enforce and maintain 90%+ code coverage using SonarQube to uphold code quality. I actively mentor developers, conduct code reviews, and collaborate directly with onsite clients to align delivery with business goals.
