Sysadmin -> DevOps
Several years experience working inside DevOps environments running Java and Python applications on Red Hat variants of the GNU/Linux OS. Solid communication and technical writing skills used for catering to any developer need for deploying and maintaining applications as well as articulating information back to management leaders. Comfortable taking on new challenges, and adept at collaborating with colleagues on complex projects. Infrastructure management experience with Ansible, Puppet, MS Active Directory, VMware vSphere, and NetApp FAS storage systems.
Recently I have been closely involved with deploying and maintaining different OpenStack environments. I have also invested a lot of time getting familiar with Python and trying to write readable and reusable code.
