What I'm looking for

I seek senior fintech or payments roles leading end-to-end implementations, certification efforts, and vendor-integrated digital transformation in an outcomes-driven, compliance-focused team.

I am a payments-focused technical consultant and project manager with over 11 years delivering payment switch systems, EMV card issuance, tokenization, and PCI-DSS compliant solutions across African banks and financial institutions. I lead end-to-end projects (Agile & Waterfall), manage vendors, and drive Visa/Mastercard certification and system integrations that improve transaction security and operational efficiency.

Across roles at Barnes International and the Commercial Bank of Ethiopia, I achieved 100% EMV and PCI-DSS compliance, supported 1M+ annual card productions, led 20+ person cross-functional teams, and contributed to $2M+ in sales closures and 15+ client onboardings. I seek senior roles in fintech, payment systems, or digital transformation where I can apply my technical, compliance, and project leadership strengths.
