Cisco Certified Network and Voice Engineer

If you are looking for an experienced Network and Voice Engineer with a strong focus on have come to the right place!!

What am I looking for?


I am looking for a location-independent job. Ideally, a position that is full WFH (Work From Home). My goal is to be able to work from anywhere while traveling with my family.

I am currently at a fantastic company with a great culture. I'm very happy! However, I am open to a job that provides the location freedom I'm looking for. I don't plan on moving companies unless it aligns with my location-independent goals.


I am always working on a certification. I have one more test left on my CCNP R/S and will move onto Collaboration certs once complete.



Routing and Switching








I maintain a helpful and encouraging blog and YouTube channel for Network and Voice Engineers. It offers support for those working on IT certifications as well as how-to articles on various voice and networking technologies.

I have over 5 years of experience with networking and collaboration technologies
