Worked on the forcedotcom/source-deploy-retrieve repository to deliver a registry extension supporting the new 'tpt' data type. This feature enables automatic recognition and handling of tpt entries, laying the foundation for future configuration and validation enhancements. The approach focused on evolving the registry’s type system and ensuring robust integration with existing deployment workflows. Using TypeScript and full stack development skills, the work emphasized code quality, incremental delivery, and clear commit-level traceability. No major bugs were addressed during this period, as the primary objective was to broaden data type interoperability and improve readiness for future deployment pipeline requirements.
