Developed and delivered a deployment-ready voice chat feature for the TerraFirmaGreg-Team/Modpack-Modern repository, focusing on enabling in-app communication through UDP port configuration within Docker Compose. The work involved authoring YAML configuration to expose the necessary UDP port, allowing real-time voice chat functionality for users and streamlining onboarding for new deployments. Leveraging DevOps practices and networking expertise, the implementation maintained clear integration steps and ensured traceability through signed-off commits and explicit issue linkage. No major bugs were reported during the period, and the feature laid a foundation for future in-game communication enhancements while minimizing changes to the existing deployment workflow.
