About Me

I’m an HPC specialist with seven years of experience in supercomputing/HPC and sixteen years experience in Linux system system administration in corporate environments. Over these years I have done kernel customization, uncountable PXE deployments, and many complex software installations. I currently have an RHCSA and am studying for my RHCE. I am highly skilled in using Bash scripting to automate complex tasks and provide tools for systems management. I have been both a member and a leader on teams of all sizes and believe that my ability to work with anyone in any situation is one of my strongest assets. My understanding of cluster management, resource management, and scheduling has allowed to me to easily hit the ground running in any environment in which I have had the opportunity to work.
