Worked on the dragonflyoss/dragonfly repository to deliver multi-storage backend support for the Preheat Job, enabling seamless integration with both object storage and HDFS systems. This involved adding configurable parameters to the preheat job, allowing deployments to flexibly handle files from multiple storage backends while reducing manual configuration steps. The technical approach focused on enhancing parameter handling to ensure correct propagation of configuration data across storage paths, aligning with ongoing efforts to optimize preheat workflows. Demonstrated backend development expertise using Go, with contributions following conventional commit standards and signed-off practices, reflecting a methodical and standards-driven approach to backend engineering tasks.
