Michal Smiarowski upgraded the CI/CD workflow for the threshold-network/token-dashboard repository by migrating artifact handling from GitHub Actions v3 to v4. This work involved updating YAML configuration files and aligning dependencies to ensure compatibility with the latest GitHub Actions standards. By addressing deprecation notices and streamlining artifact upload and download processes, Michal improved build reliability and deployment consistency. The changes reduced the risk of future build failures due to outdated actions and enhanced reproducibility across environments. Leveraging skills in CI/CD automation and GitHub Actions, Michal delivered a maintainable solution that prepares the project for ongoing automation and future updates.
