Designing human‑centered experiences in the age of AI

I'm Denis Gachoki, a senior product designer based in Nairobi, Kenya. I've spent 10 years designing products where the stakes are real — for riders, merchants, and humanitarian workers across Africa.

Experiments

Things I've built out of curiosity. Poking at AI, following a hunch, and shipping before I had all the answers.

02

Interested in working together?

I'm always open to the right collaboration — whether that's consulting, a contract role, or something you haven't named yet. Let's figure it out.

Dear potential collaborator,

I'm a product designer who goes deep — research, systems thinking, prototyping, shipped product. I don't like to be boxed in as "just a designer." I'm a builder.

I care about building things that actually work for real people — especially in African and emerging market contexts where the stakes are higher and the constraints are real.

If you're building something meaningful and need someone who thinks in systems and ships with craft, let's talk.
