The problem
Sinai region building data had no visual, interactive way to explore locations, calculate distances between points, or manage records — and needed to serve English, Arabic, and French speaking stakeholders.
My role
Responsibilities
Built both the Next.js client and the Express/Prisma API server solo, including the localization files for all three languages.
Main workflows
- 1.User registers and logs in via JWT authentication
- 2.User explores buildings on an interactive Cesium 3D map of the Sinai region
- 3.User adds or browses building records tied to map locations
- 4.User calculates distance and estimated travel time between two selected points
- 5.Dashboard surfaces summary statistics on buildings and routes
Architecture
- Decoupled Next.js client and Express API server, connected over REST
- Prisma ORM over PostgreSQL for building records and migrations
- CesiumJS powering the interactive 3D terrain map on the client
- English, Arabic, and French localization files for a trilingual interface
Security and deployment
- JWT-based registration and login
- Environment-based configuration (.env / .env.local) kept out of version control
- Cesium Ion token managed through the deployment provider's secret settings, not hardcoded
