About

I care more about the second week of use than the first impression.

I live in Giza, Egypt, and I've spent 5+ years designing complex software, mostly B2B SaaS in fintech and retail point-of-sale. I've also designed government e-services in Egypt and Saudi Arabia, for the General Administration of Traffic (Ministry of Interior) and the Royal Commission for Jubail and Yanbu.

I studied Computer Science, which makes working closely with engineers feel natural. For two years I was an external lecturer at ITI, teaching UI/UX fundamentals to front-end development trainees.

I use AI-assisted prototyping to put something testable in front of people sooner. It shortens research and competitive analysis, and helps me check whether people really need a feature before it gets built.
