What I'm looking for

I seek senior security leadership roles where I can drive governance-first strategies, build high-performing teams, and align security to business objectives in regulated environments.

I am a cybersecurity leader and software engineer with over a decade of experience architecting secure systems, driving compliance initiatives, and managing risk in regulated environments.

I align security frameworks such as NDPR, CBN, ISO/IEC 27001, PCI DSS, and NIST to business strategy, leading cross-functional programs that strengthen compliance, reduce risk exposure, and improve incident response readiness.

My technical background spans AWS cloud security, server-side JavaScript (Node.js), penetration testing, secure SDLC, and security automation; I have built platforms, audited cloud workloads, and led DevSecOps implementations.

I founded BSidesLagos, built FraudRep (an AI-powered fraud detection system adopted by African banks), developed national mobile app security standards adopted by public sector agencies, and regularly speak and train at industry events.
