What I'm looking for

I’m keen to apply my experience building secure backend platforms to healthcare technology in Africa.

At Xendnow, I lead backend architecture for an African-market remittance platform that connects banks and payment providers through one secure API. I built partner integration connectors and implemented authentication with Passkeys, TOTP, and JWT.

At Kamix, I was Tech Lead for Kamix Pay, a cross-border payments platform, where I coordinated three engineers and designed a multi-PSP microservices architecture. I’m keen to apply my fintech and backend experience to healthcare technology in Africa.
