Mustapha was excellent to work with! He is very communicative, very responsible and really great at what he does. I would recommend him highly to anyone looking for a great UI UX designer and a specialist in CRO.
Mustapha is a rare mix of UX/UI designer and conversion strategist. At ConvertLab, he turned complex ideas into clean, high-impact designs.. His product design mindset and attention to user behavior made every project sharper and more effective. Truly one of those people who just ā€˜gets it’.. I highly recommend working with him! šŸ‘

Mustapha is one of the sharpest UX, Designer minds I’ve worked with. At ConversionFlow, he drove multiple 35%+ lifts through smart A/B testing and a laser focus on user behavior. He even built our entire Airtable tracking system, making everything smoother. When our head of CRO was out, Mustapha stepped up and ran the whole program like a pro and still delivering big results..
Mustapha has that rare mix of speed and taste. He’d drop designs that looked like they took weeks — in days. Honestly, half the time I thought he was secretly cloning himself. Working with him was a blast, and the results spoke for themselves.
