What I'm looking for

I'm open to remote, Lagos-based, or relocation opportunities where I can contribute to penetration testing, SIEM and detection engineering, Zero Trust architecture, incident response, and security operations.

I've conducted full-scope VAPT for Employment Express Verband LLP partner projects, identifying critical web application and network vulnerabilities and delivering CVSS-scored remediation guidance.

Across Hacktify and Redynox, I've used Burp Suite, OWASP ZAP, Nmap, Wireshark, and Kali Linux to uncover OWASP Top 10 issues including SQL injection, XSS, CSRF, misconfigurations, and anomalous network activity. My penetration testing work achieved a 90% vulnerability detection rate across assessed systems.

I'm also building ENSOP, a self-hosted Zero Trust network lab that combines pfSense, Suricata, Wazuh, Zeek, ELK, VLAN segmentation, and MITRE ATT&CK red-team simulations for detection validation.

My projects include an Elastic Stack SIEM for correlating distributed security events, a reinforcement-learning adaptive firewall, and a NIST SP 800-207-aligned Zero Trust framework for hybrid AWS, O365, and VPN environments. I bring hands-on experience in offensive security, detection engineering, network forensics, API security, and incident response.
