Mark Onyango

@markonyango1

Software engineering leader at Untapped-Global, building multi-market payment integrations and real-time revenue reporting across African markets.

At Untapped-Global, I led the architecture and delivery of a self-service investor platform with onboarding, KYC, AML checks, ACH payments, and note purchases. I also built internal tools for real-time portfolio monitoring and managed AWS infrastructure.

I built and scaled payment integrations across African markets, and I’m currently leading a revenue reporting system with on/off-ramping of investment flows. Earlier, at Asilimia (Leja), I built backend systems for an SME financial platform and integrated M-PESA APIs and bulk SMS gateways.
