Reuben Kariuki

I'm a Lead Data Scientist in fintech with a background in Actuarial Science, currently driving credit risk modeling and data product development at FinBerry Capital in Nairobi. My work lives at the intersection of AI, growth, and financial inclusion — building models and products that move real business metrics, not just dashboards.

Some numbers that tell the story: 14% month-on-month customer growth, a 40% year-over-year increase in disbursements, and a market-research-driven product redesign that lifted monthly repayment rates by 10%.

Before FinBerry, I sharpened customer insights at Copia Global and mentored the next generation of data scientists at the African Centre for Data Science — work that shaped how I think about both technical rigor and real-world impact.

Beyond the day job, I'm deep into financial markets — forex, crypto, and the data patterns behind them — and I channel that curiosity into Friday Analytics, my weekly YouTube channel where I break down data science, fintech, and AI for a global audience. I believe good analytics shouldn't stay locked in a notebook — it should be shared, taught, and made useful.
