What I'm looking for

I’m seeking a hands-on infrastructure role where I can improve reliability, automate operations, and work with cloud-native and networking technologies in a collaborative, security-focused team.

I am an IT professional with over 10 years of experience managing network and systems administration across WAN/LAN, Cisco routers and switches, firewall appliances, and virtualization platforms. I have a proven record of improving support efficiency—about 20%—through effective ticketing workflows and by managing user accounts and access in Azure AD and on-prem directories.

I have provided hardware configuration and break/fix support under HIPAA regulations, handled incident response and remediation, and performed migrations and upgrades including Office 365 Exchange hybrid and VMWare host expansions. I also regularly use automation and tooling such as PowerShell, SCCM, PDQ Deploy, and SIEM solutions to maintain secure, compliant environments.

Recently I upskilled by architecting a multi-cluster Kubernetes homelab with staging, Flux-driven GitOps reconciliations, and Grafana monitoring to simulate production workloads. I hold certifications including Microsoft DevOps Engineer Expert, Azure Administrator Associate, CCNA, and CySA+, and I seek opportunities to apply systems, networking, and cloud expertise to improve reliability and operational efficiency.
