At Cube Software Solutions, I built ASP.NET Core order, catalog, and checkout APIs for Og Mart, with Redis caching that kept responses under 500 ms at peak traffic. I also moved order and inventory processing to RabbitMQ workflows and added payment webhooks with distributed idempotency keys.
For T7ady El 30, I designed a .NET tournament-bracket engine and pushed live game state over SignalR; the platform is live on Google Play. On Taxi Daif, I built a driver wallet and settlement ledger with ACID transactions, configurable commissions, and automatic fraud blocking.
I also delivered a multi-tenant survey platform at Dirah and built data pipelines as a Data Engineering Intern at Intelligent Systems (ISYS). Outside work, I create backend deep dives on YouTube as System Unboxed, and I placed first at the Dell Technologies AI Empower Egypt Hackathon.
