At Trego Tech, I engineered the backend of the Trego delivery app, a logistics platform connecting drivers and customers in real time. I also architected microservices for order management, tracking, driver assignments, and secure payment integrations.

I built and maintained the backend for Rabta, an AI-powered multi-channel commerce platform. Its catalog, inventory, and order services support sales across Amazon, Shopify, Noon, Jumia, Trendyol, Zid, and WooCommerce.

At Trego Tech, I developed a seller dashboard for marketplace products, orders, and analytics, contributing to the Next.js frontend that integrated with backend APIs. I also led code reviews and enforced MVC design patterns.

Previously, at InfiniaDev, I built and maintained backend services and RESTful APIs for client-facing web applications, and optimized database queries and server performance. In freelance projects, I built backends for e-commerce platforms and delivered a real-time group chat service for drivers and customers.
