The Business 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 Responsibilities

Built both the Next.js client and the Express/Prisma API server solo, including the localization files for all three languages.

Main Workflows

1User registers and logs in via JWT authentication
