01About

Engineer by trade. Builder by habit.

I'm a software engineer from Cairo. For seven years I've shipped Flutter apps for real businesses, most of them in Saudi Arabia: fintech, ERP and SaaS, government services, real estate, marketplaces and delivery.

I care most about the parts users never see: clean architecture, offline-first data, security that meets fintech standards, and release pipelines a team can trust. I lead the mobile team for the Rassd Cloud product line at World of System and Software.

I also build my own products end to end. Classawy runs attendance, quizzes and grades for universities and private tutors. Taht Elbalata is a private, encrypted savings vault for gold, silver and cash.

Taht Elbalata

تحت البلاطة

Your gold, silver and cash: one live number, in your own currency.

Many families save the traditional way: grams of gold in different karats, some silver, and cash in local and foreign currencies. Knowing what it is all worth today means checking prices, converting units and doing the math by hand, and then working out zakat on top. Taht Elbalata (“under the tile”, the Arabic idiom for savings kept at home) turns all of that into one live number.

Classawy for Universities

كلاساوي للجامعات· Formerly “Daftar”

Attendance, quizzes and grades: the whole university day on one screen.

Attendance is often a paper sheet passed around the hall, quizzes and sheets are collected by hand, and coursework grades live in a professor's private spreadsheet. It is slow, easy to game, and students rarely see how their grade was calculated. Classawy gives professors, teaching assistants and students one app for the whole term.

Classawy for Private Tutoring

كلاساوي للمجموعات· Classawy Schools

Groups, attendance, quizzes and a monthly report for parents, built for the private tutor.

Private tutors run many groups, from primary to secondary school, and often track attendance and marks in notebooks while updating parents over chat. The university product doesn't fit them: there, a university owns the courses. Here, the teacher is the business.
