Roles and Responsibilities.
* Work with Engineering, Operations, Quality Assurance and Project Management to define and execute projects that implement build, release and deployment of web software.
* Manage the source code control system.
* Develop an automated, continuous, build process that reviews the source code, identifies build errors and notifies appropriate parties to expedite/facilitate synchronization to the latest build.
* Improve productivity by designing & developing full-featured build systems; implementing tools and scripts that enable efficient, flexible builds (Shell, Perl).
* Integrated the build system to the bug tracking system.
* Develop an efficient deployment process for web deployments (rolling, hot etc.).
* Deployment and configuration management with Ansible.
* Designed the deployment architecture for deployment to Linux boxes (with no root access) from the existing deployment solution (Octopus), as well as via Ansible
