Profile

I'm a cyber security researcher with over six years of experience across the security industry and technical training. My work spans ethical hacking, digital forensics, penetration testing and network security — split between hands-on engagements and building the next generation of security professionals.

As Technical Head at Offenso Hackers Academy, I lead the technical curriculum and research direction, while also serving as Managing Partner across Offenso Hackers Academy and Dotin Digital Academy — helping run and grow both institutions.
