About Hassan

Converted Engineer to Data Analyst (Master 2 CNAM, 2025), I spent 8 years transforming industrial data into operational decisions before I even knew it was called data.
End-to-end mastery: collection (CMMS/ERP) -> cleaning SQL/Python/PowerQuery -> modeling (Star Schema) -> Power BI dashboarding -> recommendations. Rare dual profile: I understand the business behind the data.
