Top SchoolYu Sun is a Senior iOS Engineer based in Melbourne with a decade of software experience and a strong focus on mobile platforms, having shipped major features for Cash App, Afterpay and other consumer-facing products. He excels in building maintainable apps using modern architectures (VIPER, MVVM, MVC) and reactive programming across Swift, Kotlin and Rx libraries, and has hands-on experience with Objective-C and SwiftUI. At Cash App he led critical sign-in/onboarding and IDV work, drove refactors to address iOS14 deprecations and reduced binary size, and helped build internal tooling like debugging CLIs and a server-driven UI editor. He pairs product-minded engineering with mentoring and documentation, consistently improving code quality, CI/CD and automation for global releases.
