What I'm looking for

I seek a technically challenging role managing cloud or streaming infrastructure with strong incident response, security focus, collaborative culture, and opportunities to automate and improve operational processes.

I am an analytical, methodical Systems Administrator with extensive experience managing high-stress incidents and protecting sensitive information across cloud and broadcast environments.

I have led incident response and coordinated multi-team restorations for large-scale streaming and healthcare systems, improving mean time to resolution and mentoring teams to reduce SLA violations.

My technical background spans VMware ESXi, AWS, Hyper-V, Windows Server, Linux, networking (DNS, IKE/IPSEC), and scripting with Python and PowerShell, complemented by hands-on VPN, SAN, and CDN experience.

I bring strong communications skills, a focus on security best practices, and a history of building tooling and automation to streamline operations and maintain critical infrastructure integrity.
