ABOUT

I'm Chukwuebuka Akalegbere — a cybersecurity professional with deep hands-on experience across both offensive and defensive security disciplines. I bridge the gap between knowing how attacks work and building defenses that actually stop them.

My background spans penetration testing methodologies, incident response, digital forensics, and enterprise infrastructure — built through relentless self-driven learning on platforms like TryHackMe (top 1% globally) and competitive CTF competitions.

I'm pursuing my bachelor's in cybersecurity and working toward OSCP certification. I don't just study security — I build it, break it, and understand it from the ground up.
