Worked on stabilizing the build system for the zmynx/aws-lambda-calculator repository, focusing on resolving compatibility issues with the latest Python version and updated dependencies. Addressed persistent build failures in both CI and production by downgrading the Python version requirement and aligning the toml dependency, ensuring consistent and reliable deployments. Utilized skills in Python development, build management, and dependency management to validate and merge the fix, which improved the resilience of the build pipeline. This targeted engineering effort reduced failed deployments and streamlined the release process, supporting faster time-to-production and greater reliability across multiple environments for the project.
