What I'm looking for

I’m looking to lead enterprise information security governance and ISO 27001 compliance, embed security into digital products, and drive practical risk reduction through DLP, incident response, and awareness—partnering closely with technology and risk teams.

I’m an information security leader with 10+ years securing telecommunications and fintech environments. I focus on strong governance, risk management, and operational security leadership to protect sensitive customer and financial data.

As Manager, Information Security at MoMo from MTN, I lead the Information Security governance and compliance program for the fintech business. I oversee the ISMS and drive ISO 27001 compliance through internal reviews and external audit engagements, while translating enterprise security policies into day-to-day operational practice.

I bring hands-on expertise in security programs that reduce insider risk and strengthen detection. I’ve managed Data Loss Prevention (DLP) to monitor sensitive data movement, investigated and triaged DLP incidents with root-cause analysis, and supported security incident investigations in collaboration with the Cyber Security Operations Center.

I’m also committed to building a security culture through awareness and stakeholder enablement. I champion security-focused training and advisory support for technology and product teams, and I mentor others through the CyberGirls Fellowship with CyberSafe Foundation.
