TES provide services to the education industry and professionals. Within TES I worked for the THE (Times Higher Education) division which focuses on Universities and produces the World University Rankings.
I was a remote-based team leader of a small team of four (all remote) covering front-end and back-end development in D8 and D7. I focused mostly on back-end development. This was a continuous integration environment, with a strong framework of process and control implemented with tools such as platform.sh, Jenkins, Git, Github and Zenhub, and with code review and coding-standards to the fore.
https://www.timeshighereducation.com This is the main THE website, a Drupal 7 and Drupal Commerce development in multiple languages (English, French, Chinese), and with heavy use of Panels, workflow, and extensive access controls.
Other in-house systems Drupal 8-based proxy system for gathering job specifications from external systems, storing in a SOLR repository, and providing a REST interface for the main THE website to consume, integrated with Madgex and Parsehub.
Related projects I also worked on a migration of email contact data from Salesforce (ExactTarget) into Mailchimp and the integration with the THE website.
