What I'm looking for

I'm looking to apply offensive application security, banking security, cloud-native security, and risk assessment experience to help teams identify complex vulnerabilities and deliver practical remediation.

At Deloitte Nigeria, I assess enterprise web applications, APIs, mobile apps, payment switches, core banking platforms, middleware, and cloud workloads for vulnerabilities that create real business risk. I combine automated testing with deep manual assessment across authentication, authorization, business logic, cryptography, and architecture.

I've also strengthened security monitoring, GRC, and audit programs, improving MTTD by 25% and MITRE ATT&CK detection coverage by 30%. Earlier, I built a fraud detection system that reduced false positives by 60% and delivered secure software development workshops.
