Reyvem Johnson Cajegas is the Founder of RedSocCyber, an ethical hacker, cybersecurity instructor and IT Security Manager based in California.

I am a Computer Engineer and graduated in 2024 with an Associate’s Degree in Health Science from Pasadena, California. I started my career in technical support for 2 years and then worked in healthcare for almost 7 years. After that, I moved into cybersecurity, where I worked as a Cybersecurity Teaching Assistant, Test Engineer, and later became a Cybersecurity Instructor. I teach military veterans and immigrants, and I also teach part-time for a college in Australia and a university in Pennsylvania, USA. I also created a course about Android Systems Security for an internship program. I later became an IT Security Manager, where I lead a small team and handle IT and security operations. I manage cloud systems in Azure and AWS, Microsoft 365, user accounts, Microsoft Defender, Google Workspace, ConnectWise tools, POS systems, and system migrations. I also worked at a Managed Service Provider as a Cybersecurity L2 and L3, where I handled incident response, patching, vulnerability assessments, and penetration testing. I have experience using tools like Splunk, SentinelOne XDR, and Blumira. I also have industry certifications, join CTF challenges on TryHackMe and Hack The Box, and contribute to Telus AI.
