I've investigated a compromised web server through CyberDefenders Blue Team Labs, reconstructing a complete attack chain from network capture data. I identified a UNION-based SQL injection vulnerability and traced exploitation through database enumeration, credential compromise, and malicious file upload.

I turn technical investigation into actionable reports, including risk analysis, attack timelines, and remediation recommendations. My published incident report reflects my focus on practical defensive security work.

In my home lab, I've performed vulnerability testing and service enumeration using Kali Linux, Nmap, and VirtualBox. I identified an end-of-life kernel and an unnecessarily exposed service, then documented hardening recommendations in a risk report.

At African Leadership University, I work directly with stakeholders, produce leadership-approved proposals and governance documents, and deliver client-ready work under tight deadlines. I'm building on this foundation through the Google Cybersecurity Certificate and CompTIA Security+ studies.
