Experience
| Twitter Inc. |
San Francisco, CA |
7/2011 - 10/2015 |
| Software Engineer, Build Team |
4/2012 - 10/2015 |

In April of 2012, I joined a newly formed team at Twitter focused on developer productivity. During
my time on this team, I performed a variety of duties, ranging from maintaining internal git and
Reviewboard services, maintaining our use of maven in a large scala repository, and helping to
maintain Pants, Twitter’s home-grown build
tool. Along the way, I worked on projects to convert said scala repository from maven to pants, integration
work to upgrade pants, and worked on getting Twitter into a monorepo, with a true monobuild. I also
wrote documentation, developed training courses (that I frequently delivered inside of Twitter),
and provided excellent support to our customers. During this time, I worked on a number of side
projects, including revamping on Twitter’s internal people directory, including adding a
feature to support employee recognition.

| Software Engineer, Release Team |
7/2011 - 4/2012 |
|
As a release engineer at Twitter, I was part of a team responsible for daily deploys of Twitter’s
frontend Ruby on Rails application. This entailed not only performing deploys, but also performing
light QA and site reliability functions, as well as oncall support. I also helped to maintain
several in-house tools (written in everything from Ruby, to Rails, to Java). Finally, I was part of
a small team that built out a new test environment, building a complete copy of Twitter from
scratch. This effort involved learning how to install and configure every layer of Twitter’s stack,
including discovering service dependencies, rewriting config files, and figuring out how to
bootstrap the system with enough data in order to be useful.

different software stacks (one Java/Tomcat, the other PHP/Lighttpd) in two separate managed
facilities. I built or maintained the following: alert monitoring, performance monitoring, oncall

Production Engineering, I was part of a team that built custom software for
EDS global operations. This included writing new functionality in Perl

reuse, and supportability. I also promoted next-generation communications
technologies to promote easier collaboration, including: blogs, Wiki, and
RSS.
