What I'm looking for

I seek senior network or cloud-network roles focused on resilient enterprise architectures, security-first operations, capacity planning and opportunities to lead infrastructure modernization.

I am a seasoned ICT networking professional with over 10 years of hands-on experience designing, deploying and managing enterprise and ISP networks. I hold CCNA, CCNP, CCIE (written), AWS Solutions Architect–Associate, a BSc (Hons) in Information Systems and an MBA, and I deliver resilient network designs, firmware upgrades, security appliance implementations and cloud networking solutions.

I have worked as a Senior Network Engineer and Network Architect across financial, ISP and telecom environments, leading NOC operations, large-scale routing/switching (BGP, OSPF, EIGRP, MPLS), wireless and fiber projects, and AWS VPC implementations. I prioritize reliability, capacity planning and security while driving continuous improvement and operational excellence.
