GrabIT

A food delivery platform with five different kinds of user on it, which is really a permissions problem wearing a delivery app costume. Most of the work went into the access control and into keeping the tracking map honest while an order is moving.

What was built

• Built a multi-vendor platform supporting 5 user roles on secure REST APIs, with JWT-based role-based access control deciding what each role can reach.
• Implemented live delivery tracking and customer support using React-Leaflet for the map and Socket.IO for the updates.
• Designed the admin dashboard on MongoDB aggregation pipelines, covering analytics, restaurant approval and moderation.
• Added a Google Gemini chatbot that resolves common customer queries without a human in the loop.
• Wrote tests and checked code quality across the API surface.
