Message

At Banque Extérieure d'Algérie, I developed and compared machine-learning models for credit scoring using real credit data. I designed a two-level classification approach and a stacked ensemble, then used SHAP to interpret the results.

During my internship with ELITE / Sonelgaz, I participated in securing a Data Center network infrastructure. I configured and secured Cisco switches, including VLAN segmentation, access controls, SSH, and NTP.

I also built an interactive Power BI project comparing Netflix, Prime Video, and Disney+ catalogs. I transformed the data with Power Query and created DAX measures, KPIs, and dashboards; personal cybersecurity projects include Active Directory, pfSense, and SIEM.
