Message

At STARNEWS / MOBILE XL, I lead Growth & Performance Marketing across three markets, coordinating acquisition, creative, social media and content teams with Product and Technology. I built a structured digital acquisition engine beyond a historically SMS-led model.

At NEERO - FINTECH, I owned full-funnel Virtual Visa Card acquisition, optimizing campaigns against activation signals and tracking the customer journey through first transaction. The product grew from 0 to 500K+ downloads, with 150K+ MAU and 25K+ daily transactions.

At GLOTELHO - E-COMMERCE, I owned acquisition across search, shopping, social and programmatic channels; monthly online revenue grew from ~50K FCFA to ~900M FCFA during scale-up. I also lead the digital marketing department and teach part-time at FLEXACADEMY.
