Applications and Integration Architect at POSB, shaping a biller platform connecting 15+ billers across digital banking channels.
What I'm looking for
At POSB, I own the architecture of the biller-engine integration platform, connecting 15+ billers across USSD, mobile and internet banking. I define its integration patterns and design for resilience, security and high availability.
At Zim-TTECH, I led development of the PrEP module used across 1,000+ facilities and integrated laboratory systems with the EHR using REST and FHIR. Earlier at Telecel Zimbabwe, I worked on the *480# USSD integration and Telecash mobile-money services for 500,000+ customers.
