I turn banking, retail, health, and industry data into decision-ready dashboards and insights.

What I'm looking for

I'm looking to turn complex business data into reliable dashboards and actionable insights, while collaborating with technical and business teams on data-driven projects.

I've analyzed and structured data for Colmart Grand Est, BNI Madagascar, and Axian Group, turning multi-source business data into reliable insights, dashboards, and operational decisions.

Using SQL, Python, and Power BI, I clean and model data, identify trends and anomalies, and translate business needs into usable analyses. I've also supported fuel-billing digitalization and Odoo ERP data integration at Axian Energy – Jovena.
