Who I am

Turning Data Into
Business Value

I don't just crunch numbers — I engineer clarity from complexity. Over 5+ years of applied data science and software development, I've delivered 20+ projects that moved the needle: predictive models that slashed churn by double digits, dashboards that cut reporting time by 70%, and analytical pipelines that unlocked revenue opportunities worth thousands.

My sweet spot? The intersection of machine learning, business intelligence, and full‑stack execution — where algorithms meet ROI. From A/B testing and demand forecasting to building the tools that make insights accessible, I bring the rare ability to both architect the solution and explain it to anyone in the room.

I've worked across retail, engineering, digital marketing, and education — always with a single obsession: make data work for people, not the other way around.

Based in Nairobi, working with clients everywhere. Let's turn your data into your biggest competitive advantage.

Beyond the work

What Drives Me

The interests and perspectives that shape how I think, work, and collaborate.

Motorsport

Motorsport & Strategy

F1, Le Mans, WRC Safari Rally. I'm drawn to the intersection of split‑second strategy, precision engineering, and real‑time data. That same discipline — fast feedback, clean execution — shows up in how I approach analytical work and model tuning.

Engineering

Engineering & Design

I enjoy well‑designed systems — whether it's a power unit or a data pipeline. That engineering mindset translates into clean architecture, maintainable code, and solutions built to last rather than just to ship.

Music and culture

Music, Books & Film

Music, literature and cinema are how I reset and stay curious. I read plots the way I read datasets — looking for structure and meaning beneath the surface. That habit of extracting narrative from noise flows directly into how I communicate insights.

Football and teamwork

Football, Teams & Community

Football, for me, is about tactics, roles, and shared goals — the same things that make a great project team. Between mentoring students, teaching STEM, and working with clients, I see myself as a builder of people as much as a builder of products.
