Worked on the microsoft/graphitation repository to address a critical issue in dependency management, focusing on improving the correctness of dependency resolution for non-semver versions in yarn.lock files. Delivered a targeted bug fix that resolved incorrect version range handling for @apollo/client, ensuring that dependency graphs remain deterministic and reliable. This change enhanced build stability by reducing the risk of flaky CI failures and unpredictable installs, directly benefiting downstream consumers. Demonstrated expertise in dependency management and YAML, applying a precise, bug-focused workflow to align dependency resolution with semver expectations and support more reproducible, collaborative development across related projects and teams.
