linux vmware powercli within .net fmwk

As of late, I have been involved in the design and implementation of an HPC modeling environment. This was accomplished utilizing vmware, linux, and windows, using powercli within the .net framework. I can automate any level of building out virtual DC's, clusters, resource groups, processing and storage down to VM's, creating the orchestration layer down to individual system processing. I have been an IT professional for 20+ years with much accumulated knowledge in system administration, storage, programming, backups, infrastructure, performance analysis, etc. Able to work in a group or individually. Self starter, motivated, not much oversight or direction needed after reviewing and understanding the project(s) at hand. I follow through on everything with attention to every level of detail. I will be up and running in hours or days for most engagements! Sheriff's Department : days Broward College : hours South Florida Water Management District : hour

Experienced developer and sysadmin (linux)

Been employed as a hands on Infrastructure Manager since 2006. Interact on a daily basis with senior developers and have been writing and debugging code since 1998. Currently working for a US software company liasing with developers and building out production customer-facing infrastructure. Have previously had 6 years experience in the web hosting industry with varied and broad experience - everything from networking to systems to development. I am one of those people who crosses the chasm between system administrator and developer and I'm generally employed in a berth that allows me to architect or lead groups of people to deliver a project which requires intense configuration on both sides. Particularly interested in scaling challenges. I still develop software, write web applications and run my own web servers and mail servers. I have been doing this since I was 15 for my own enjoyment. Speciality: Linux
