Experience

Senior Build and Release Engineer

Vendini

September 2014 – Present (11 months)

Researched, experimented and proposed new development to deployment process using Docker and wrote scripts to encapsulate the current LAMP (Linux, Apache, MySQL and PHP) stack with Docker. Experimented with Docker and Ansible together and then just using docker-compose. Determined that a set of Docker containers, each for a specific portion of the stack in use was more effective than a monolithic Docker container.

Researched several ways to expedite moving forwards from an old PHP environment to a newer one with fewer security vulnerabilities without feature loss. Determined that having a set of Docker containers with different versions of PHP would facilitate the developers in getting the features already in place to be compatible with more recent versions of PHP.

Maintenance of existing build and release scripts, policies, procedures and documentation.

Administrating the private GitHub git repositories and access to the repositories.

Accumulating the individually QA-approved bugfix and feature branches into the release candidate branch.

Deploying to production the QA-approved release candidate.

Developing and maintaining accurate, positive and prompt communication with Member Services, Engineering, Product Management and DevOps.
