TheBlackBox
Local-first personal control center & modular widget platform. Freeform draggable canvas, schema-driven manifest widget engine, client-side AES security vault, and hybrid Supabase realtime sync.
Productivity workflows fragment across dozens of disconnected web apps and browser tabs.
Productivity workflows fragment across dozens of disconnected web apps and browser tabs. Existing dashboard tools are either rigid, static grids with fixed built-in widgets or cloud-locked admin panels that introduce network latency on everyday actions and expose private API credentials in unencrypted cloud databases.
Architected a local-first freeform widget canvas (react-rnd + Zustand) with multi-canvas switching, snap-to-grid, independent mobile deck ordering, and instantaneous optimistic persistence to localStorage.
Engineered an extensible manifest-driven widget engine: decoupled runtime execution from UI manifests, enabling schema-driven custom widget authoring, JSON import/export portability, and a custom API widget with deep JSON response path inspection.
Built hybrid cloud synchronization over Supabase PostgreSQL: implemented an offline mutation queue with debounced background pushes, soft-delete reconciliation, and Realtime WebSocket multi-device sync.
Implemented client-side vault encryption & server-isolated OAuth: encrypted third-party API tokens in local state before disk persistence, and quarantined Google OAuth tokens strictly in server-side HttpOnly cookies with on-demand refresh helpers.
