What I'm looking for

I'm looking for a data-focused role where I can build reliable dashboards, improve data quality, develop predictive solutions, and communicate actionable insights that support business decisions.

I've analyzed operational and client data at Orange Cameroun and AFG Bank Cameroun, building Power BI dashboards, improving data quality, and translating findings for operational teams and leadership. My predictive model identified sales points at risk of revenue decline a month in advance with 87% accuracy.

I've also trained a YOLOv8 urban-damage detection model and deployed a Streamlit visualization app at Spartes Robotics. Earlier, I built Laravel APIs and MySQL database structures at Best Consulting Sarl, bringing a practical foundation in data integration and web development.
