At z2data, I design and develop scalable ASP.NET Core microservices and web applications using Clean Architecture and Domain-Driven Design. I build resilient REST and message-driven services with RabbitMQ, optimize SQL Server and MongoDB workloads, and secure APIs for Angular and React front ends with JWT and OAuth2/Identity Server.

I've also delivered .NET systems including Ta3lom Ibn Khaldun Schools, AFAAQ ERP, TOP QUDRAT Certificates Platform, Shop Retail Canteen, Charities System, and Generic Timetable. Across z2data and HelpTk, I've owned Docker, Kubernetes, Azure, and CI/CD workflows while leading code reviews and mentoring junior developers.
