About Me

Turning Ideas Into Bug-Free Experiences

I am a dedicated Software QA Engineer studying Computer Science and Information Systems at El Saleheya El Gadida University. With hands-on experience in building Android applications using Java, I look beyond the surface of manual testing to truly understand the software architecture beneath.

I leverage this technical development background to design rigorous, edge-case test scenarios, helping businesses deliver flawless, user-centric software that protects their brand reputation and saves development time.
