Welcome to my network engineering portfolio! I'm Joe Poyzer, a Service Desk Engineer III with almost 7 years of experience in managed services, network administration, and technical support. This site showcases my hands-on projects, lab environments, and technical documentation as I continue to grow my expertise in enterprise networking.

Throughout my career, I've worked across diverse industries including managed services, manufacturing, hospitality, and entertainment, giving me a well-rounded perspective on how networks support different business needs. I specialize in designing, implementing, and troubleshooting complex network infrastructures with a focus on routing, switching, automation, and cloud integration.

Currently, I'm pursuing my Cisco CCNP Enterprise certification and actively building lab environments to explore advanced networking concepts. This portfolio documents my learning journey and demonstrates practical implementations of technologies I work with daily.
