Developed end-to-end testing automation and continuous integration workflows for the adobecom/events-milo repository, focusing on streamlining quality assurance and deployment processes. Leveraged YAML and GitHub Actions to create a configurable run-e2e-tests workflow supporting multiple environments, test suites, and browser jobs. Introduced a reusable trigger-circleci workflow to invoke CircleCI pipelines with required parameters and secrets, enabling cross-environment test execution. The work established a scalable CI/CD automation foundation, reducing manual testing and accelerating feedback cycles. Emphasis was placed on workflow orchestration and environment parametrization, preparing the repository for broader adoption and easier onboarding of future multi-repository end-to-end testing initiatives.
