Mohamed Abdo

Backend software engineer specializing in Node.js, Express, and NestJS, with hands-on experience building RESTful APIs, real-time systems, and scalable backend architectures.

I've built and shipped backend systems across multiple domains — a ride-booking platform (Darbi), an e-commerce API with Stripe integration, an event management platform, and Workout Hacker, an IoT-powered AI gym assistant where I handled all backend engineering including MQTT-based device communication and Socket.io real-time updates.

I recently refactored the Workout Hacker backend from JavaScript to TypeScript, improving type safety and long-term maintainability — a decision I made independently to raise the codebase's quality standard.
