TRASHANDLER: Waste Collection & Vendor Management Platform

I built and delivered the Seller & Vendor mobile modules. I turned Figma designs into production-ready Flutter screens and implemented order management, tracking, chat, maps and real-time movement.

• Modules: Seller & Vendor
• Platform: Flutter mobile app

What I built

Order management

• Implemented order management for sellers and vendors, including order details, status updates and tracking screens

Real-time tracking

• Built real-time order and movement tracking over WebSocket, so the app shows live movement and status changes

Maps & routing

• Integrated Google Maps and location features for order tracking and pickup and delivery workflows

In-app chat

• Implemented in-app chat so the users involved in an order can talk to each other at every stage

Figma to Flutter

• Converted detailed Figma designs into responsive Flutter interfaces with consistent layouts, components, spacing and interaction patterns
• Wrote production-quality Flutter code built around reusable widgets, maintainability and responsive layouts

API-driven screens

• Connected the UI to backend REST APIs and handled data, loading states, error states and dynamic screen rendering
• Managed state with Riverpod, structuring it so new features are easy to add and maintain
