Worked on backend stability improvements for the puppetlabs/puppetlabs-puppet_agent and OpenVoxProject/puppet repositories, focusing on dependency management and JSON handling using Ruby. Addressed a dependency conflict by constraining the orchestrator_client gem to avoid Bundler resolution issues, which reduced build-time failures and improved CI reliability. In OpenVoxProject/puppet, maintained consistent JSON formatting after a gem upgrade by preserving newline behavior for empty arrays and hashes, and added regression tests to ensure formatting consistency. Emphasized robust testing and traceability to minimize regression risk, demonstrating a methodical approach to backend development, dependency management, and Ruby gem maintenance across multiple codebases.
