Introduction

I am Network Engineer with extensive experience of Cisco’s Catalyst Center / Software Defined Access and Catalyst switching platforms. Adept at troubleshooting routed, switched and wireless networks, Linux and Windows systems, micro-services deployment, AAA and server infrastructures technologies.

I am looking for a career opportunity in which I can leverage my existing skillset, as well as expand my knowledge of other aspects of ICT, such as data centers, virtualization and automation.

I enjoy working in a structured environment with clear documentation that can help to collaborate more efficiently. I am a hard worker who doesn’t shy away from the unknown but sees it as a possibility to learn.
