01 · About

Security, from the SOC floor
to the attack surface.

Results-driven Cyber Security Specialist with 3+ years of hands-on experience in 24/7 SOC operations, incident response, and internal penetration testing. I've helped harden a national banking environment — from triaging live threats in Splunk to leading offensive assessments that shrink the attack surface before attackers find it.

Backed by top-tier certifications (CEH v13, eWPT, CompTIA PenTest+) and a track record of actively participating in phishing incident reduction through workflow optimisation and a security-first culture.
