What I'm looking for

I seek a technical role supporting enterprise systems and networks with emphasis on uptime, security, documentation, and collaborative incident resolution.

I am an ICT Infrastructure and Systems Support Officer with enterprise-level experience supporting mission-critical systems, networks, and secure data environments. I provide L1 and L2 technical support, network troubleshooting (LAN/WAN), endpoint and server administration, and cybersecurity hardening within regulated environments.

My background includes roles at Kenya Revenue Authority (Service Support), KNEC (Data Capturer), the Ministry of Education (ICT Intern), and ICT Authority at Machakos University, where I supported high-availability systems, performed root cause analysis, and documented operational procedures. I hold certifications including CCNA, CCNP, Cisco CyberOps, Google IT Support, and Google Cybersecurity.
