I am a Linux systems engineer focused on high-performance computing, automation, and reliable infrastructure. I prioritize clarity, autonomy, and durable solutions with a preference for stability and human-readable tooling.

At a university HPC collaboratory I diagnosed CMOS failures across 600+ nodes, created boot recovery protocols and lifecycle tracking, worked with vendor support to streamline ticket workflows, and deployed Ansible and ReFrame to validate node health and configuration consistency.

As a freelance research computing administrator I provided remote Linux system support, configured cluster login nodes and scheduling environments, wrote onboarding documentation, and developed scripts and workflows for system checks, software installs, and user environment snapshots.

On personal projects I design LAN-wide VPN routing, device classification with DNSMasq, and ARM Kubernetes lab automation using cloud-init, Ansible, and Parallels. I build tooling for observability, remote power control, and reproducible CI loops to ensure reliable cluster provisioning.
