• Support and maintain essential services that support core mission applications, proactively enhancing their availability, performance and stability.
• Find innovative solutions to problems, automating repetitive work; ensure support does not exceed 50% of the time.

  Linux and Windows command lines (Bash, Power Shell); cloud infrastructure (AWS, Azure, Open Stack); deployment tools (Chef, Puppet); monitoring stacks (ELK); containerisation (Docker); automation testing (Selenium); micro-services architectures.
