E-commerce Mobile App & Web Admin Dashboard

A production-grade, end-to-end e-commerce platform engineered for high-growth retail businesses — combining a feature-rich web admin dashboard with a performant cross-platform mobile storefront that works seamlessly together in real time.

Overview

This project replaced a fragmented legacy system struggling with inventory accuracy, slow order fulfilment, and a poor mobile experience. The solution spans two surfaces — a Next.js web dashboard for operations and a Flutter mobile app for customers — unified through a shared Firebase backend and a clean REST API layer. The outcome was a 35% reduction in order processing time and a measurable uplift in revenue.

Core Features

• Inventory management — Bulk product uploads, variant support, low-stock alerts, and live count sync across all channels.

• Analytics dashboard — Revenue charts, conversion funnels, top-selling products, and exportable reports all in one view.

• Real-time order processing — Live order queue with status tracking, fulfilment workflows, and customer notification hooks.

• Cross-platform mobile storefront — Flutter app with smooth animations, cart persistence, guest checkout, and push notifications for iOS and Android.

• Role-based access control — Granular permissions for admins, managers, and staff with full audit trail logging.

• Offline support — The mobile app stays functional without connectivity, queuing actions and syncing automatically when back online.

Technical Architecture

• Next.js + Tailwind CSS powers the admin dashboard — server-rendered for fast initial load, fully responsive across desktop and tablet.

• Flutter with BLoC architecture separates business logic from UI into clean, testable layers — keeping the codebase maintainable as the product scales.

• Firebase handles real-time sync, authentication, and push notifications — delivering instant updates across all devices without polling.

• REST APIs define a clean contract between frontend surfaces and backend services, making integrations straightforward to extend or replace.

• Designed for horizontal scalability — stateless API handlers and Firebase's distributed infrastructure absorb traffic spikes during campaigns or seasonal peaks with no extra configuration.
