8+ years. 1M+ users. 30+ countries.
I turn constraints into products people trust.
The fintech platform processing M-PESA payments for smallholder farmers. The civic tech election system where trust had to be the architecture, not a feature. The ILO methodology that needed to work on a feature phone, not just in a training room. I do the messy work between the idea and the shipped product — and I stay for what comes after.

How I bridge technical complexity and user reality.
01. Ground truth
Field interviews and ethnographic research in low-bandwidth, high-constraint contexts.
02. System arch
Pragmatic data schemas, API contracts, USSD fallbacks, and offline sync mechanics.
03. Ship cycle
Tight weekly iterations, engineering unblocking, telemetry, and automated audit trails.
04. Unit adoption
Unit economics, payment recovery rates, merchant retention, and organizational trust.
Start a dialogue
Every engagement starts with a conversation.
If you're building something that needs a product person who has shipped under real constraints, I'd like to hear what you're working on.
