I specialize in React Native, Flutter, Swift, Kotlin, JavaScript, and TypeScript, and I focus on creating clean, reliable, and user-friendly mobile products. I have worked on production-ready applications across fintech, e-commerce, healthcare, and SaaS, where I contributed to architecture, API integration, performance optimization, and modern UI/UX implementation. I enjoy turning complex requirements into intuitive mobile experiences that perform well across devices and platforms. In my recent roles, I developed and launched mobile applications using React Native and Flutter, built scalable cross-platform architectures, and integrated RESTful and GraphQL APIs for authentication, payments, analytics, and real-time synchronization. I also implemented push notifications, biometric authentication, in-app purchases, and secure OAuth workflows. I have strong experience collaborating with UI/UX designers, backend engineers, and product teams to deliver polished interfaces and stable releases. I have also handled App Store and Google Play deployment pipelines, testing, release management, CI/CD automation, debugging, and crash monitoring. My technical background includes mobile frontend development, native module creation, backend integration, and cloud services such as Firebase, AWS, Google Cloud, and Azure. I am comfortable working in Agile environments and contributing across the full mobile development lifecycle. I hold a Bachelor’s degree in Computer Science from The University of Hong Kong. I am based in the United States and I am open to full-time mobile engineering opportunities where I can continue building impactful mobile products. ## Professional area ### [Developer & Engineer](https://jobicy.com/resume-category/dev.md) ## Skills ### [Agile](https://jobicy.com/resume-skill/agile.md)[AWS](https://jobicy.com/resume-skill/aws.md)[Azure](https://jobicy.com/resume-skill/azure.md)[CI/CD](https://jobicy.com/resume-skill/ci-cd.md)[Docker](https://jobicy.com/resume-skill/docker.md)[Express.js](https://jobicy.com/resume-skill/express-js.md)[Figma](https://jobicy.com/resume-skill/figma.md)[Firebase](https://jobicy.com/resume-skill/firebase.md)[Flutter](https://jobicy.com/resume-skill/flutter.md)[JavaScript](https://jobicy.com/resume-skill/javascript.md)[Kotlin](https://jobicy.com/resume-skill/kotlin.md)[Kubernetes](https://jobicy.com/resume-skill/kubernetes.md)[Mobile Development](https://jobicy.com/resume-skill/mobile-development.md)[MySQL](https://jobicy.com/resume-skill/mysql.md)[Node.js](https://jobicy.com/resume-skill/node-js.md)[PostgreSQL](https://jobicy.com/resume-skill/postgresql.md)[React Native](https://jobicy.com/resume-skill/react-native.md)[Scrum](https://jobicy.com/resume-skill/scrum.md)[Swift](https://jobicy.com/resume-skill/swift.md)[Testing](https://jobicy.com/resume-skill/testing.md)[TypeScript](https://jobicy.com/resume-skill/typescript.md) ## Education Sep 2015 - Apr 2020 Bachelor's degree in Computer Science @ The University of Hong Kong (HKU) ## Experience Nov 2024 - Feb 2026 Senior Mobile Developer @ Kansas City Defender Developed and launched multiple high-performance mobile applications for fintech, healthcare, and e-commerce clients using React Native and Flutter.
