What I'm looking for

I am seeking hands-on cybersecurity roles where I can perform penetration testing and incident response, work within collaborative teams, and continue developing technical expertise and certifications.

I am a junior penetration tester and IT security professional with practical experience in vulnerability assessment, penetration testing, and endpoint protection. I have performed hands-on testing with tools like Nessus, Metasploit, and Wireshark to identify and remediate critical security issues.

During a cybersecurity internship, I supervised deployment of Data Loss Prevention controls and configured ModSecurity rulesets, significantly reducing exposure to SQL injection, XSS, and data leakage. I have delivered measurable improvements in email security and spam/phishing reduction using Proofpoint solutions.

As an IT support/IT manager, I implemented and maintained endpoint protection across 158 workstations, resolved hundreds of incidents, and supported over 500 end users while maintaining high customer satisfaction. I contributed to malware incident reduction and introduced policies for patching and phishing risk reduction.

I hold multiple Cisco Networking Academy certifications and NITDA digital literacy credentials, and I am completing a BSc in Mass Communication and Media Studies. I am detail-oriented, adaptable, and committed to improving organizational security posture through pragmatic, measurable controls.
