Summary
🤩
Rockstar🎓
Top SchoolLouise Hsu is a Software Engineer III with eight years of experience building web and iOS applications, currently contributing to Flutter.dev at Google. A UBC computer science graduate, she combines front-end expertise in React, TypeScript, HTML/CSS and JavaScript with native mobile experience in Objective-C, Swift-adjacent tooling, and backend languages like Java, C#, and Python. At Google she has deep, practical impact on Flutter’s iOS platform and engine—adding native selection controls, Look Up/Share integrations, and fixing platform-specific crashes and localization issues. Her open-source contributions include substantial work on flutter/packages (local_auth, pointer_interceptor, in_app_purchase) where she implemented iOS features, improved biometric error handling, and migrated StoreKit flows to pigeon. Former roles at Microsoft, Amazon Robotics, and startups show a pattern of rewriting legacy tools into modern, maintainable React-based systems and shipping production-ready features. Motivated and curious, she blends meticulous platform-level engineering with a user-focused product sensibility.
