Message

At MFS Africa / Onafriq, I redesigned the merchant onboarding journey using Jobs-to-be-Done research, a design sprint, and usability testing. The new flow reduced average onboarding time by about 38% and related support tickets by 33%.

I also evolved Onafriq UI, a Figma design system implemented as a React component library, and designed a high-fidelity prototype for bulk payments. In my contract work at Nairobi Digital Agency, I designed and developed responsive client websites and built a React product configurator that contributed to a 40% increase in qualified leads.
