Worked on the flipt-io/flipt-client-sdks repository to deliver Python 3.9 compatibility for the flipt-client-python SDK, focusing on runtime expansion and improved CI reliability. Addressed onboarding and production risks by updating the pyproject.toml to specify Python 3.9, ensuring that packaging and tooling aligned with the new environment. Refreshed the Docker image used in testing to include Python 3.9, which enabled consistent validation across different environments. Adjusted testing commands to accurately specify SDKs, improving test coverage and reducing false negatives in CI pipelines. Utilized Python, Go, and CI/CD practices to streamline upgrades and support safer, more reliable deployments.
