What I'm looking for

I’m aiming to become a reputable Network and Security Administrator in Tanzania and globally, applying my networking, security, and IT infrastructure expertise to improve business efficiency and security.

At Watu Credit, I support and maintain company computer systems and network infrastructure, including routers, switches, and firewalls.

I troubleshoot network issues, perform system installations and updates, and maintain local call center infrastructure. I also implement security measures and assess network performance.

Previously, as a Network Administrator (Intern) at Tanzania Library Services Board (TLSB), I monitored servers, networks, applications, and databases, and conducted security audits.

At Institute of Heavy Equipment and Technology (IHET), I designed and implemented network architecture, deployed firewall configurations and intrusion detection systems, and conducted penetration testing and vulnerability assessments.
