DevOps Software Engineer @ From December 2013 to Present (2 years) San Francisco Bay AreaDevOps Software Engineer @ As the DevOps engineer at Topsy, I create software that allows our systems engineers to greatly increase their productivity. My primary focus is automating processes that were previously cumbersome or manual for those employees. * Implemented an extensive API for Racktables (http://racktables.org), allowing it to become the definitive source of truth for hardware assets at Topsy. * Created a set of scripts for automatically generating system configurations: DNS records, switch configs (rancid), monitoring * Developed a suite of systems around Racktables which make it self-correcting (SNMP queries compared against Racktables records). * Improved our installation of the Cacti monitoring system by modifying the polling component, allowing it to run twice as many queries per five minute polling period. * Current work includes multiplexing our Cacti poller to allow it to scale horizontally, adding more change detection logic to Racktables, and creating a usage reporting portal for our external customers.
