During April 2025, Sw1843 focused on stabilizing the build system for the zmynx/aws-lambda-calculator repository. Addressing persistent build failures, Sw1843 implemented a compatibility fix by downgrading the Python version requirement and aligning the toml dependency to ensure seamless integration with the latest Python release. This work involved careful dependency management and build management, resulting in a more reliable CI/CD pipeline and reducing failed deployments across environments. Using Python as the primary language, Sw1843 validated and merged the fix, improving build resilience and ensuring that both CI and production environments could consistently produce successful builds for the project.
