Welcome to my technical portfolio! I'm Joe Poyzer, a Service Desk Engineer III with 7 years of experience in managed services, network administration, and technical support. This site showcases my hands-on projects, lab environments, and technical documentation across networking, systems administration, virtualization, and Azure.

Throughout my career, I've worked across diverse industries including managed services, manufacturing, hospitality, and entertainment, giving me a well-rounded perspective on how technology supports different business needs. I specialize in designing, implementing, and troubleshooting complex network and systems infrastructure, with growing depth in cloud and virtualization technologies.

Currently, I'm pursuing my Cisco CCNP Enterprise and Microsoft Azure Security Engineer Associate certifications, and actively building lab environments to explore advanced networking, virtualization, and cloud concepts. This portfolio documents my learning journey and demonstrates practical implementations of technologies I work with daily.
