Personal Projects
El Niño Tracker
2026 – Present
Creator • rahbjee.github.io/enso-tracker
- Designed and built a live, map-first tracker of how the 2026–27 El Niño reaches California's coast, testing whether warm water raises the sea there through tide gauges, beach widths and storm swell
- Engineered an idempotent Python pipeline (DuckDB, pandas) that ingests public NOAA, NASA, USGS and Scripps data alongside Google's WeatherNext 3 wind forecasts via Earth Engine
- Graded each verdict against decades of past winters, every finding linked to its test and sources — measured history, not a forecast
- Automated the data refresh and site rebuild with GitHub Actions, published to GitHub Pages as an interactive Leaflet map with a guided tour
Markit Marketplace
2016 – Present
Creator • markitplace.org
- Designed and built a crowd-sourced, map-based marketplace connecting local farmers, artisans, and small businesses directly with consumers, across devices: live on the web, on the App Store for iPhone, and in beta on Android
- Developed the native iOS client from scratch using Swift, Xcode, and Apple Maps SDK, featuring real-time location-based product discovery
- Architected a serverless backend using Firebase (Firestore, Authentication, Cloud Functions, and Google Analytics) to support dynamic inventory updates and user messaging
- Piloting the platform with local vendors and consumers in Detroit and San Francisco to bridge the gap in local food systems accessibility
