About Me

I’m Grishon Muthee, a Cybersecurity Specialist with a Bachelor's Degree in Aerospace Engineering. Although I earned my Bachelor’s degree in Aerospace Engineering, my passion for technology and computing ultimately led me to transition into cybersecurity, where I found my true professional calling. My engineering background has been instrumental in shaping my analytical thinking, problem-solving ability, attention to detail, and systems-based approach to complex challenges. Today, I combine that engineering mindset with hands-on cybersecurity expertise to solve security problems with both technical depth and structured, strategic thinking.

My cybersecurity expertise spans Penetration Testing, Web Security, Linux and Windows Security, Python Programming, Network Technologies, Malware Analysis, SIEM, and broader cybersecurity operations. I hold Multiple Certifications across various cybersecurity domains and have distinguished myself as a Highly Skilled Capture The Flag (CTF) solver, ranking within the top 5% globally on platforms such as TryHackMe, PicoCTF, Hack The Box, and Root-Me. My hands-on experience includes configuring and deploying security tools, conducting malware analysis, and performing physical and digital security assessments.
