About

Professional summary

I am a results-driven backend engineer focused on building scalable, secure, and high-performance systems. I specialize in developing production-grade APIs with NestJS and Clean Architecture, and I enjoy working on solutions that are maintainable, reliable, and aligned with business needs.

I have hands-on experience across the full backend lifecycle, including system design, API development, authentication, performance optimization, and testing. I have also worked with real-time features and AI integration, which has helped me build practical systems that support modern product requirements.

In my recent contract role at HealLink, I contributed to a healthcare platform by working on request workflows, connection features, QR modules, and real-time chat functionality. I designed and implemented RESTful APIs using NestJS while applying clean architecture principles to improve scalability and maintainability.

I have also worked as a freelance full stack developer on a restaurant management system, where I built tools for order tracking, cashier operations, and inventory workflows. I developed a real-time order dashboard using WebSockets and optimized MongoDB queries to improve response times and operational efficiency.

Beyond client work, I have built several notable projects, including an AI knowledge hub for document management and semantic search, an enterprise authentication template, and a medical management backend. These projects reflect my interest in modular architecture, security, and production-ready engineering practices.

I am currently pursuing a B.Sc. in Information Technology at Egyptian E-Learning University and hold certifications including Cisco CCNP and AWS Certified Cloud Practitioner. I am fluent in Arabic and proficient in English, and I am based in Cairo, Egypt.
