Background
I hold a degree in Industrial Design, with over 7 years of experience evolving into product design and UX strategy.
My work sits at the intersection of:
— Product strategy & UX leadership
— Complex system design (fintech, SaaS)
— Cross-functional alignment (product, engineering, business)
Experience
I've led UX strategy and product direction across multiple products — at Telescope, defining the MVP and designing key workflows like billing, payroll, and EVV to improve operations, and at Cellulant, driving end-to-end design for Tingg Checkout across 20+ African markets, reducing drop-offs by 35% and scaling the design system for speed and consistency.
At Neptune Software, I led design across digital banking and lending platforms, increasing engagement by 40% and adoption by 30%, while improving engineering turnaround by 50% through stronger alignment.
Across these roles, I've focused on simplifying complex fintech and SaaS systems, building scalable design systems, and working closely with product, engineering, and business teams to deliver measurable results across markets.
