Messy data in.
Clear answers out.

I’m Ziad. I study Data Science and AI in Cairo, and I build models, dashboards and apps that people can really use.

Why guess?

Numbers can answer most questions. I help them speak in simple words.

W

What?

Machine learning models, data analysis, Power BI dashboards and small web apps.

H

How?

I clean the data, test ideas, then explain the result in plain words.

01 · About

Curious by default.
Useful by design.

My journey started with one simple question: how can data solve real problems? Since then I have been learning Machine Learning, SQL, Power BI and Python, and turning raw numbers into something useful.

What I care about most is the impact behind a model or a dashboard: understand the problem, find the story in the data, and ship something people use.

“Data isn’t just numbers — it’s a chance to understand, improve and create.”
