At Orascom Development, I contributed to a real-time location tracking and geofencing system used to monitor security personnel across development sites. I implemented location validation by checking GPS coordinates against assigned geographic polygons and worked with GeoJSON datasets and spatial database queries.
At ICPC Sohag Community, I mentor trainees in C++ and Data Structures & Algorithms through problem-solving sessions, code reviews, and up-solving contests. I also teach algorithmic techniques and time and space complexity analysis through hands-on practice.
I built Talabat, an e-commerce backend API with ASP.NET Core and Clean Onion Architecture. It includes Redis distributed caching and Stripe payment processing with server-side idempotency and distributed locks to prevent race conditions.
