Worked on the aio-libs/aiohttp repository to address a compatibility issue affecting Python 3.14 during linting. Focused on dependency management, the developer implemented a targeted guard to prevent the installation of backports.zstd when running linting workflows with Python 3.14, thereby reducing CI flakiness and avoiding potential test failures. This change was carefully scoped to the linting dependency resolution process, ensuring that compatibility with earlier Python versions was maintained and no regressions were introduced. The work demonstrated proficiency in Python development and dependency management, contributing to a more stable and reliable continuous integration environment for the project.
