Fatma Hammami
@fatmahammami
Junior Data Engineer at Cdiscount, where I developed customer segmentation tested in CRM A/B campaigns.
What I'm looking for
At Cdiscount, I extracted and transformed multi-source customer data with SQL/Snowflake, Python, and Power Query, then prepared and validated it for analysis.
I developed a customer segmentation framework using behavioral and transactional data. The solution was tested through A/B tests in CRM campaigns, and I presented the project to senior stakeholders at the Data Client Committee.
I also automated recurring data processing with Power Query and built data models, KPIs, and dashboards with Power BI and DAX. I investigated data anomalies and inconsistencies to improve the reliability of results.
At CRESE – UMLP, I prepared and analyzed survey and economic data using R, and explored economic data and evaluated predictive models using Python and R. I’m looking to develop my Data Engineering expertise, especially in scalable data processing and data reliability.
