I have been working in Drupal for 7 years. I am a backend developer and system administrator but also do frontend work when needed.
I have created continuous deployment systems for companies I have worked at in the past. I have created these systems through multiple means, straight git integration, Jenkins and bash, usage of drush, Aegir Hostmaster system with Custom modules I wrote to integrate with github service api calls, combinations of the aforementioned. I can execute and/or advise how best to implement your plan. I am well-versed in this subject and have expert knowledge in system administration, Drupal/Drush/Aegir, and version control systems.
Please let me know if you have questions about any of my experience. I have scripts to bring to this project as well.
Updating proposal with details I wrote in message to you:
I have experience with continuous deployment and specifically with drupal. I can work with you on how you might want to do your integration and how your teams workflow is. I will help in writing the Jenkins scripts and rollback procedures for deployments and setting up everything. We will need to determine what your needs are.
