Product · Design · Business · Execution

I figure out what to build. Then I make it real.

I’ve spent 12+ years across product, design, strategy and business, from hands-on 0→1 work to executive product leadership. I work the full problem: users, proposition, experience, commercial logic and delivery. AI is part of how I execute when it helps me stay closer to the product, not a substitute for judgment. That combination is how unclear opportunities become products people can actually use.

Lead & Scale

Product leadership at scale.

I have led Product and Design inside regulated, high-growth companies, where the constraints are teams, compliance and scale, not only the idea.

Fingo Africa · Consumer banking
Co-CPO / Product & Design Leadership

Built and scaled consumer banking in Kenya from zero.

Fingo Africa was regulated consumer banking, not a short experiment. As Co-CPO I owned Product & Design across strategy, experience, growth and execution.

Fingo Pay · B2B payments
Product strategy & execution

Merchant experience, payments operations and revenue in the same decision.

Fingo Pay is a separate B2B payments platform. Product decisions cut across merchant experience, infrastructure, operations and commercial reality.

  • Merchant tools & payment links
  • Invoices & reconciliation
  • Payments infrastructure
  • Commercial / pricing validation

SafeBoda · Mobility
Design leadership

Led design for a high-growth mobility product at scale.

At SafeBoda I led a four-person design team inside a high-growth mobility / super-app environment. Less time on my own screens. More time making sure the team was solving the right problems for a product that reached 1M+ users.

How I work

Stay close to the product decision.

When the answer is unclear, long chains of translation slow everything down. I stay close to the work: decide what should change, shape it, put it in front of users, and keep going until the next decision is clearer.

Usual path

Too many handoffs between the idea and the product.

By the time something reaches users, the original thinking has been translated several times.

Closer loop

See it. Change it. Test it. Keep going.

Most useful in 0→1 and experiments, when waiting costs more than learning.

UnderstandDecideBuildTestChange
What does not change

Speed only helps when the judgment is good.

Moving faster does not replace knowing which problem matters, what feels wrong, or what is worth changing next.

Product

What problem is worth solving? What should we stop building?

Design

Does this make sense to people? What feels wrong?

Business

Does this create value? What evidence decides the next move?

Execution

Getting from decision to something real: with teams, or hands-on with AI-assisted development when that is the fastest way to learn. Not a replacement for engineering organisations.

AI is useful leverage in the build. Knowing what to change, and what not to, still comes from product and design judgment.

That is where 12+ years across product, design and business matter.
How to read the work

Three kinds of evidence.

Each piece of work shows a different part of the same skill set: building a product, testing it with users, or leading it at scale.

Selected work

Live products. Real users. Real evidence.

Afritesting and BallBrain are live products, from first build through pilot evidence with real users.

Build · Afritesting · B2B research platform

From idea to working platform in six days.

I wanted to know whether companies in Kenya would pay for easier access to local research participants. Instead of spending weeks on a concept deck, I built a live product and tested the premise.

Test & Learn · BallBrain · Basketball training

From hypothesis to a real academy pilot.

Could individual basketball training be more structured for players without constant coach access? I built the Android app, recruited players, ran a closed beta, and tested it for six weeks with Deementor Academy in Nairobi.

Where I am useful

Three ways this skill set usually shows up.

Same foundation (product, design, business and execution), shaped to the problem.

01

Lead

CPO / VP Product / Head of Product

Senior product leadership that connects strategy, design, business and execution, and keeps the organisation on the right problems.

Product strategy & roadmapTeam leadershipOperating modelsDesign leadershipGrowth outcomes
When leadership needs to stay close to the product, not only the process.
02

Build

0→1 / New Ventures

An important opportunity exists, but the product is still unclear.

Opportunity discoveryProduct strategyUX / service designMVP developmentGTM experimentation
When ambiguity is the problem, and waiting is expensive.
03

Experiment

Focused product experiment

A company is about to spend serious time or money on an idea that can be tested before a full commitment.

OpportunityInsightHypothesisWorking experimentEvidenceKill / iterate / invest
When the decision is expensive, and opinions are not enough.
Next step

Bring me a problem without an obvious answer.

That is usually where I do my best work: understand what is going on, cut through the noise, get something real in front of users, and keep going until the next decision is clearer.

Open to

Product leadership · 0→1 · New ventures · Focused experiments

Remote-first or flexible. Selected project work as well.

If the problem matters, I want to understand it properly, then get to something real as fast as possible.

I’ve spent 12+ years across product, design, strategy and business, from messy 0→1 work to executive roles. I notice when something does not make sense. I use AI where it speeds up execution. I would rather test than debate for weeks.

Most interested in fintech, new products, and teams that need someone who can lead and still get close to the work.
