Yo, I’m Brian Kimathi, a cybersecurity and IT systems enthusiast from Kenya, passionate about building secure digital environments and improving the world through technology. With over 6 years of hands-on experience in system administration, cybersecurity operations, integrations, mobile money systems and more, I’ve worked on everything from securing backend infrastructures to helping companies respond to real-world cyber threats. My journey has taken me through diverse roles—system administrator at East African Data Handlers, privacy analyst at Techno Brain, senior systems analyst at Bowmans Law and tens of consulting roles.. Along the way, I’ve consulted on projects across the banking, telco, and social impact sectors. I enjoy getting my hands dirty with SecOps tools, system analysis, and threat response frameworks, but what drives me most is helping others understand and embrace the power of secure technology. I hold a Bachelor’s degree in Computer Security and Forensics, certifications in networking and cybersecurity, and I’m currently exploring global opportunities in cybersecurity and infrastructure. This blog is my little corner of the internet where I share security tips and tools, deep dives into IT systems and processes, stories from real-world projects, and mentorship advice for young professionals in tech. If you're into tech, security, or figuring out this digital world you’ll feel right at home here. Let’s connect, learn, and grow together.
