Mobile-first Progressive Web App for saving and organizing YouTube videos, built as a personal project for my wife. The application registers as a Web Share Target on Android, allowing users to share YouTube links directly from the YouTube app's share menu into their personal collection. Architected with React Router 7 for full-stack SSR, Prisma ORM for database access, and PostgreSQL for persistent storage. Implemented drag-and-drop reordering using @dnd-kit with a responsive grid layout optimized for mobile (3 columns) and desktop (7 columns). Integrated deep-linking via YouTube's URI scheme to open videos directly in the native YouTube app, with web fallback for non-Android devices. Deployed on Kubernetes with Helm charts and GitHub Actions CI/CD. Features Google OAuth authentication, dark/light theme matching OS preferences, and a minimalist design philosophy — no algorithms, no recommended feeds, just the content you choose to save.
