A learning management system for managing courses, learning materials, and several exam formats. Code submissions are executed and graded automatically through Judge0 with hidden and public testcases. Used OpenFGA with the ReBAC model for fine-grained access control across users, groups, courses, learning materials, and files/folders.

A somewhat Google Map-like app but only for public transit such as buses or trains with data scraped and processed. Implemented route navigation using Dijkstra's algorithm, supporting multi-route transfers, distance calculation, and travel-time estimation. Users can track and receive notifications about their favorite routes via email or push notifications. The admin page can manage route data, stations and traffic reports.

Another trivial healthcare booking system with three roles: patient, doctor, and admin.
