What I'm looking for

I seek hands-on roles in network, systems, or cloud infrastructure with a security-first culture, opportunities to automate processes, and room for technical growth.

I am an IT professional with over 10 years of experience in network and systems administration, focused on IP subnetting, WAN/LAN management, and Cisco router/switch configuration. I combine hands-on network engineering with cloud identity and cybersecurity practices to deliver stable, secure infrastructures.

In recent roles I analyzed and automated electronic medical records workflows, supported high-volume immunization registry tasks, and provided public-facing technical support under tight deadlines. I have implemented SCCM and Meraki solutions, managed firewalls (SonicWall, Checkpoint), and administered Cisco VoIP systems to reduce incidents and improve operational efficiency.

I hold multiple certifications including Microsoft DevOps and Azure credentials, CySA+ and PenTest+, and maintain a homelab with Linux, Docker, and Kubernetes to continually sharpen my skills. I take a practical, security-first approach and enjoy translating technical complexity into reliable solutions and clear end-user guidance.
