  • Jun 2010 - Oct 2017

  I am in the Service Engineering and Operations group as a Linux System Administrator (`Service Engineer'). Although I began with operating system and Yahoo! specific software configuration on FreeBSD and RHEL production hosts, I quickly moved into developing automation software in mostly Perl and to a lesser extent Python and Bash to speed up and help simplify the job of administering systems at the scale of tens of thousands of hosts. The software that I've written is a mix of functional and object oriented Perl using many data sources - MySQL databases, XML (in SVN), various RESTful APIs, and Bugzilla. Most of these are Linux command line tools with the exception of a project that used the YUI (Javascript and CSS) for it's frontend interface. Some examples of what I've coded are: Scripts to audit hosts during procurement to ensure that HW and SW match the specification dictated by the host's role. Automations to generate external requests required by hosts immediately after datacenter installation. This includes load balancer configuration, DNS registration, and interfacing with myriad other proprietary Yahoo! systems. Program to determine if hosts were in the proper state to retire them from use in production. This eliminated a slow, error-prone, and tedious 24 step manual process. In addition to my system administration duties, I started the Yahoo Makerspace - a collaborative space in which employees can create using 3D printers, milling machines, textiles, screen printing, wood and metal working tools. Personal and business critical items were fabricated here, serving needs in complimentary ways.
