Project Overview

The DODUAE e-commerce platform is a large-scale retail system designed to handle high-volume online sales, multi-role operations, and seamless integration with mobile applications. The platform supports a complete digital commerce ecosystem including storefront, order management, supplier coordination, and internal business operations.

As part of a team of 10 developers, I contributed to the development and maintenance of both frontend and backend systems using OpenCart and custom PHP solutions. The platform also powers Android and iOS applications through API integrations, ensuring a consistent and scalable experience across web and mobile.

What Was Built

  • Full-scale e-commerce platform built on OpenCart with extensive customisation
  • Advanced product catalogue with categories, attributes, sizes, colors, and reviews
  • Elasticsearch-powered search with analytics for trending and high-conversion products
  • Custom One-Page Checkout and Guest Checkout systems for improved user experience
  • Purchase Order Management System for suppliers and internal teams
  • Multiple role-based dashboards (Admin, Customer Service, Marketing, Seller, Supplier, POS, Accounts, Warehouse, etc.)
  • Graphical dashboards for sales analytics, trends, and performance tracking
  • Dynamic size chart system with category-specific and product-specific configurations
  • Seller document management system with expiry tracking and automated notifications
  • Custom email template system for marketing and transactional communication
  • Integration with WhatsApp and Email APIs for real-time order notifications
  • RESTful APIs for Android and iOS mobile app integration
  • POS system integration for managing in-store and online sales data

Technical Challenges

One of the biggest challenges was maintaining a unified backend system that supports multiple platforms, including the website and mobile applications (Android and iOS). Ensuring data consistency, API reliability, and synchronized business logic across all platforms required careful architectural planning and continuous optimisation.

Another major challenge was managing a complex and evolving codebase across a team of 10 developers. This included maintaining clean coding standards, optimising database performance, and ensuring smooth coordination between multiple modules such as orders, inventory, suppliers, and dashboards used by different departments.

System Architecture

The system is built on a customised OpenCart architecture extended with core PHP, supporting both web and mobile ecosystems. It integrates multiple internal systems and dashboards, handling large-scale data operations and real-time business workflows across departments.

  • OpenCart-based architecture with extensive custom PHP module development
  • Frontend built using HTML, CSS, Bootstrap, JavaScript, and jQuery
  • MySQL database for managing products, orders, users, suppliers, and transactional data
  • Elasticsearch integration for advanced search and analytics
  • REST APIs for Android and iOS applications
  • Third-party integrations including payment gateways, WhatsApp API, and email services
