What I'm looking for

I'm seeking a backend or cloud engineering role where I can optimize high-throughput systems, improve CI/CD and reliability, reduce cloud costs, strengthen security, and collaborate in an impact-driven team.

I build and optimize scalable backend systems that prioritize performance, reliability, and cost efficiency. I have driven optimizations that produced up to 3X faster API responses and reduced cloud spend by over $12K/month while proactively managing security and system resilience.

I design robust architectures and secure authentication flows, producing technical documentation and multi-cloud deployments that handle high throughput (1,500 requests/second). My projects include a scalable real-time chat platform, an AI-powered Discord assistant, and a private cloud storage Android app.

I hold a Bachelor’s Degree in Computer Science from Ain Shams University (ranked 3rd in class) and I continuously improve delivery through CI/CD, containerization, monitoring with Sentry and DataDog, and collaborative, outcome-driven work.
