About me

The person behind the pipelines

I'm a Data Engineer based in Tunis. I started out in business and statistics, spent a few years teaching math, and somewhere along the way realized what I actually loved was building data systems — pipelines, ETL workflows, dashboards that people rely on to make decisions.

That led me to a Master's in Data Analytics and into some genuinely interesting work. At IMPACT Initiatives I build data infrastructure that supports humanitarian operations in Sudan. Before that I developed NLP pipelines at VERMEG in fintech, automating email classification at 92% accuracy.

I care about data that does something real — not just dashboards that look nice, but systems that hold up under pressure and actually get used.

Academic background

Education

A Finance background gave me a strong sense of how data drives decisions — the MSc in Data Analytics was a deliberate pivot to build the technical depth to act on it.
