Apple ( Apr. 2015 – Current)

Cleaned up, templatized, and modernized monitoring infrastructure, going from an unmaintained Nagios 3.x installation to Icinga, Graphite, Graphana, and NLMA-ng. Quintupled the number of checks and integrated alerting with our existing paging system. Upgraded an existing, unmaintained Atlassian stack (JIRA, Confluence, Fisheye/Crucible) to the latest versions, migrated to SSO (Crowd), added Git support (Bitbucket Server) and moved from an older server in a closet to a highly secure environment in a DC, all with no downtime or interruption in service. Became the Subject Matter Expert (SME) on a new internal tool, helped architect the stack, wrote documentation, deployed it, and maintained it in production, within 2 months of starting. Became the SME on an existing service that is used world-wide by Apple, taking over duties including reviewing configuration, deploying, monitoring, and troubleshooting. Mentored junior members of the team, in both technical and social/personal matters. Helped transition multiple projects from SVN to Git, including training and coaching developers who had never previously used Git.
