Lyfe: Cross-Platform "Life OS" & Productivity Ecosystem
Mar 2026Designed as a comprehensive personal operating system, I engineered a cross-platform application (iOS and Web) that unifies task management, health tracking, and interactive brainstorming. Leveraging an AI-accelerated development workflow—combining Cursor’s IDE contextual awareness with Anthropic’s Claude Code agentic CLI—I rapidly architected and iterated on a cloud-first ecosystem capable of real-time, cross-device synchronization.
The application features a modular design encompassing a Pomodoro-driven task manager, a robust health and fitness tracker capable of managing dynamic data sets (macros, strength sets, and cardio metrics), and a smart habit-tracking system. A standout technical achievement within the app is a custom-built, Miro-style interactive whiteboard. By implementing a strict, state-driven layered architecture using react-native-svg and react-native-gesture-handler, I successfully resolved complex gesture-clashing, allowing users to seamlessly alternate between freehand vector drawing and dragging absolute-positioned UI elements (Post-it notes) on a touch interface.
The system is built on a React Native (Expo) foundation, utilizing Firebase Authentication and Firestore NoSQL for a secure, serverless backend. I architected an optimistic UI data flow leveraging React state and Zustand, enabling instant interface updates that feel lightning-fast while asynchronously syncing to the cloud in the background. To bypass traditional App Store bottlenecks and streamline personal deployment, the web variant is deployed via Firebase Hosting as a Progressive Web App (PWA), offering a persistent, native-like iOS experience complete with Google OAuth integration and offline caching capabilities.
