Background

From consumer scale to enterprise complexity

I spent my first 2 years at Safaricom PLC designing consumer products for millions of users, then shifted focus to enterprise systems where the real challenge lies in managing complexity without losing clarity.

My work sits at the intersection of strategy, systems, and interaction design. I've led design on multi-tenant enterprise tools and contributed to consumer experiences used by tens of millions of people.

I’ve redesigned digital experiences to improve usability and drive adoption, led research that informed product strategy, and worked in cross-functional teams to translate insights into meaningful impact.
