Worked on the singer-io/tap-shopify repository to enhance CI/CD workflows and maintain compatibility with the latest Python standards. Updated the CircleCI configuration to run on Python 3.12, ensuring the project leveraged new language features and security improvements. Improved the reliability of the test suite by replacing deprecated assertEquals with assertEqual, aligning with current Python testing practices and reducing potential test failures. The work focused on Python development and testing, utilizing both Python and YAML to manage configuration and automation. These updates contributed to a more robust continuous integration process and streamlined ongoing development for the repository’s maintainers and contributors.
