Worked on the Helidon repository to improve the reliability of Docker image builds by addressing a case sensitivity issue in Dockerfile mustache templates. Focused on correcting the capitalization of the 'as' keyword to 'AS' within multi-stage build templates, ensuring that Dockerfiles generated from these templates are parsed correctly by build tools. This change reduced the risk of build failures and minimized noise in continuous integration pipelines. Utilized skills in Dockerfile syntax and template management with Mustache, demonstrating careful attention to detail in template-driven automation and contributing to more robust and maintainable build processes within the Helidon project.
