What I'm looking for

I’m looking to support a mission-critical environment where I can secure and automate enterprise infrastructure, own endpoint and network reliability, and improve uptime through strong troubleshooting, documentation, and process improvement.

I’m a results-driven Systems Administrator with 6+ years of experience supporting enterprise and mission-critical IT environments across commercial, healthcare, and military sectors. I manage infrastructure, resolve complex system and network issues, and keep secure, high-availability environments running reliably.

I’ve built strong expertise in Active Directory, endpoint lifecycle management, and network support, backed by hands-on automation and process improvement. In fast-paced service environments, I reduce downtime by diagnosing root causes and delivering dependable technical solutions while maintaining SLA targets.

My experience spans endpoint imaging/deployment, secure migrations, and mission-focused network operations, including Cisco UCM VoIP and cybersecurity controls. I bring a documentation-first approach—creating SOPs and knowledge base materials—to improve team efficiency and reduce repeat issues.
