Waste Management System

Municipal waste collection is often inefficient. Trucks follow static routes regardless of bin fullness, leading to wasted fuel on empty bins and health hazards from overflowing ones that were missed. Additionally, citizens lack a direct channel to report spot-dumps.

I developed a centralized Role-Based Ecosystem to handle the complex logistics of waste collection:

• React + Vite: For a high-performance, lag-free dashboard experience.
• Node.js & Express: To handle concurrent requests from multiple users (citizens and admins) efficiently.
• Context API: Used for global state management of user sessions and authentication flows without Redux bloat.
• Leaflet Maps: For lightweight, open-source visualization of bin locations.

• Dynamic Reporting: Citizens can upload geo-tagged images of waste, instantly creating tickets for admins.
• Role-Based Access Control (RBAC): Secure separation of driver, citizen, and admin privileges.
• Status Tracking: Real-time updates on report resolution (Pending -> In Progress -> Resolved).

Challenge: Concurrency Handling
Multiple users reporting issues simultaneously caused database locks with the initial SQLite setup.

Solution: I migrated to a robust backend architecture using connection pooling in Node.js to manage high-throughput requests without latency.

IoT Integration (Planned): The next major iteration will introduce Smart Bins equipped with IoT ultrasonic sensors.

These sensors will transmit real-time fill-level data to the dashboard, allowing for fully automated route generation—dispatching trucks only when bins are near capacity, further reducing operational costs.
