About Me

Think Like an Attacker. Build Like a Defender.

Charles Otugeh

Penetration Tester & Secure Software Developer

I hold a Bachelor's degree in Statistics and Computer Science with professional experience spanning cybersecurity, ICT infrastructure, software development and data analytics.

My focus is identifying vulnerabilities before attackers exploit them through penetration testing, secure application development, vulnerability assessments and threat analysis.

I have worked with organizations in healthcare, government and software engineering while continually improving my offensive and defensive security skills through Hack The Box, TryHackMe and real-world labs.
