I'm a fullstack developer with hands-on experience building production-level web and mobile applications from the ground up. My strengths lie within React and its ecosystem (Redux, Expo, Gatsby, etc.). I'm familiar with React design patterns, best practices, newer features, testing, optimization, and how to implement them in real-life situations. I've also had backend practices building RESTful APIs following a microservice architecture with Node.js, MongoDB, and GraphQL, as well as going serverless with Firebase.
Sample Projects
Creator/senior developer of React PWA Eloqua, made in collaboration with my protégée—junior developer Layla. Highlights: full player control from notification, many-to-many relationship data on Firestore, filter thru speaker/topic/keyword, playlist, favlist, loop, playback speed switch, dark mode.
Creator of 'BIAO!: StoryMap', a React Native mobile app to help people follow stories that highlight the locations of a series of events, built on Expo with TypeScript. Highlights: close integration of Google Maps SDK, GeoJSON data, modal and tab views; marker clustering to improve visibility and performance; drawer navigation; dark mode.
I led the remake of the discontinued Natara Quanto for Palm OS into a React Progressive Web App for modern smartphones. Highlights: actionable notification, 2-level drag-n-droppable categories, filterable data visualizations, big list lazy-loading, user auth, and data backup with Google Firebase.
Static Gatsby site. Highlights: dynamically generated pages from markdown files, isotope filter layout, blog pagination, and blog commenting / subscription / form handling via 3rd-party API integrations.
