MARWAN MAMDOUH

Software EngineerFull-Stack JavaScriptBackend Developer

I've engineered production infrastructure for high-traffic platforms — from multi-channel e-commerce systems and real-time auction engines to government news platforms — across Qatar, Kuwait, Egypt, and remote Gulf teams.

My stack runs deep on Node.js, .NET, and Express.js, but my real strength is architecture: designing event-driven microservices, optimizing SQL queries for large-scale datasets, and building OCR pipelines and WebSocket engines that hold up under peak load.

I've shipped across the full delivery lifecycle: API design, AWS infrastructure, CI/CD with GitHub Actions, and integrating legacy systems with zero downtime. I don't just write code — I design systems that scale.
