Early-career cybersecurity analyst specializing in vulnerability assessment, penetration testing, and incident response.
NigeriaWhat I'm looking for
I am an early-career cybersecurity analyst with hands-on experience in vulnerability assessment, penetration testing, and incident response, grounded in OWASP Top 10 and MITRE ATT&CK frameworks. I have standardized forensics workflows, supported incident response, and performed network and web application testing that reduced recurring vulnerabilities and critical findings.
I maintain a strong practical foundation through labs and CTFs (top 8% on TryHackMe), build vulnerable labs to validate detections and remediations, and publish technical walkthroughs to explain exploit chains and mitigations. I hold formal training in cybersecurity and am completing CompTIA certifications while pursuing professional growth in both offensive and defensive security roles.
