At The Pika Africa Network Limited, I lead end-to-end design across four mobile and web products. As sole designer of Pika Retailer App, I led research-driven redesigns linked to a 2x improvement in retention.

I designed and co-developed PikaView, a data intelligence dashboard supporting $15K+ in monthly recurring revenue from enterprise clients. I use PostHog analytics to guide iteration with product managers and engineers.

Previously, I designed logistics, marketplace and fintech experiences at Hephi Studios, Telesoftas NG and Nebulla, The Creative Studio. My work spans user research, usability testing, design systems and frontend technologies including HTML, CSS, JavaScript and React.
