What I'm looking for

I seek a hands-on cybersecurity role focusing on penetration testing, threat intelligence, and incident response at a learning-focused, security-first organization that values clear communication and continuous growth.

I am a passionate Information Security Analyst and Penetration Tester with over two years of hands-on experience identifying, exploiting, and documenting vulnerabilities across web applications, networks, APIs, and mobile platforms.

I have delivered vulnerability assessments, penetration tests, source-code reviews, malware analysis, and incident response work using industry-standard tools such as Burp Suite, Metasploit, Nmap, Wireshark, Splunk, Any.run, and VirusTotal.

I have trained and mentored learners as a Cybersecurity Tutor and Awareness Trainer, performed threat intelligence research, and produced actionable reports that translate technical findings to non-technical stakeholders.

I hold multiple industry certifications (including LPT, CEH‑P, CASA, ACP, QCS, ISC2 CC, and ISO/IEC 27001 Information Security Associate), and I am committed to continuous learning and strengthening organizational security postures.
