About

I'm a cybersecurity professional with 3+ years of experience in security training, penetration testing fundamentals, and self-directed research. I currently work as a Cybersecurity Researcher at Offenso Hackers Academy, building attack simulation labs and training the next generation of security professionals.

My technical skills in ELK Stack, SIEM monitoring, and threat detection were built entirely through independent hands-on research — deploying real infrastructure, writing working tools, and studying real attack scenarios. Everything in this portfolio is something I built or investigated myself.
