Hi, I’m Charlie 👋

Software & data builder · Nairobi, Kenya
Schemas before scripts. Meaning before motion.

I design clear, thoughtful systems — the kind that make sense to humans as much as they do to machines. I care about schema-first design, reproducible analytics, and small, meaningful improvements over noisy activity.

Areas I enjoy building in

FinTech & Risk
Environment & Social Economics
Mathematics & Education
Health Systems
Governance, Gender & Society
History, Literature & Language
