Approach

Good design starts before the pixels.

03Make complexity feel simple
04Design, test, refine

I don't design screens. I design the experience between them.

About

Designer by profession. Creative by nature.

Rhythm, structure, timing, and knowing when to leave space.

I've always been curious about how things work, and how they make people feel. I came to product design from a degree in Chemistry Education at the University of Lagos, which taught me how people learn and where they get stuck.

Outside the screen I make music, play piano and trumpet, and take photographs. Different disciplines, surprisingly similar thinking: rhythm, structure, timing, emotion, and knowing when to leave space.

I've worked with cross-functional teams to drive a 30% improvement in user satisfaction on key projects.
