Developed and delivered the MJML Email Template Compilation Option for the shopware/docs repository, focusing on enhancing the Shopware CLI’s build process. This feature enabled automated MJML processing of email templates during builds, allowing early detection of template issues and reducing the risk of runtime email failures. The work leveraged skills in CLI development, MJML, and email template management, with supporting changes in Markdown and YAML. Collaboration with co-authors ensured code quality and cross-team alignment, while minor polish commits addressed grammar and wordlist sorting. The result strengthened CI feedback loops and improved the reliability of customer communications through robust template validation.
