A build server bot I made with integrations for Slack (including workflows), Teamcity, and Plastic.
My work on Buildy:
Support for Slack Workflows which include the ability to trigger builds, and initiate a workflow once a build has been completed or a commit has been made to a branch
Developed a Node JS module for Teamcity with support for fetching configurations, triggering builds, and callbacks for when builds are complete
Developed a Node JS module for Plastic SCM with support for getting basic repo information and performing commits and merges
