Worked on the Dify Plugin Daemon repository, focusing on configuration management and maintainability improvements using Go and DevOps practices. Delivered a feature that introduced configurable environment variable loading, replacing internal dotenv loading with a more flexible approach. Refactored dotenv usage by substituting magic strings with constants, which improved code clarity and reduced the risk of configuration errors. These changes streamlined deployment and testing processes across different environments, lowering both startup and runtime configuration risks. Maintained dependency hygiene after a rebase by restoring unrelated changes, ensuring codebase stability. The work emphasized reliability and maintainability in configuration management for the project.
