About me

The person behind the pipelines

I'm a Data Engineer based in Tunis. I started in finance, spent three years teaching math, then made a deliberate move into data — not just analysing it, but building the systems that make analysis possible: pipelines, ELT workflows, schemas designed to last.

That led me to a Master's in Data Analytics and into work that matters. At IMPACT Initiatives I build the data infrastructure powering Sudan response operations — field-to-dashboard pipelines that humanitarian teams depend on daily. 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 dashboards that look nice but break under load, but pipelines that are reliable enough for field conditions and fast enough for operational deadlines.

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.
