Key Projects & Technical Contributions

SIGINT (In Development) | Bun, React 19, Canvas 2D, Web Workers, IndexedDB, Docker, Heroku

Open-source real-time OSINT intelligence dashboard with interactive 3D globe visualization. Ingests live data from 7 sources: OpenSky Network (aircraft), aisstream.io (AIS vessels via persistent server-side WebSocket), USGS (seismic), GDELT 2.0 (geolocated conflict/crisis events), NASA FIRMS (fire hotspots), NOAA (severe weather alerts), and aggregated RSS news feeds. All rendering offloaded to a dedicated Web Worker with OffscreenCanvas for 60fps performance. Features a correlation engine performing cross-source spatial-temporal matching with grid-indexed O(n) queries, anomaly detection against rolling 7-day regional baselines, and composite-scored alerting. Multi-pane layout system (binary split tree, drag-to-swap, named presets) with 8 pane types including entity dossier, intel feed, alert log, and live HLS video. HMAC-SHA256 token auth (HttpOnly cookies), per-IP rate limiting, IndexedDB caching with staleness management, and PWA with offline support.
