During October 2025, Sung Kim developed and integrated the Sunbow Cleaner Service into the IndicoDataSolutions/tf_cod repository, focusing on automating cloud-native maintenance and credential governance. Leveraging Azure, Terraform, and HCL, Sung enabled scheduled maintenance tasks through Azure Cron Jobs, reducing manual intervention and supporting operational reliability. The implementation included assigning a dedicated service account for secure credential and resource management, aligning with DevOps best practices for cloud infrastructure. This work enhanced both security and scalability by embedding automation directly into the cloud environment, demonstrating a solid understanding of infrastructure-as-code and cloud-native automation within a production-grade repository.
