Worked on the hiero-ledger/hiero-sdk-java repository, focusing on enhancing maintainability and configurability within the Java codebase. Delivered a refactor that separated configuration parsing from client initialization by introducing an inner Config class, allowing for robust client creation based on configuration data from strings or readers. This approach improved testability and set the stage for future extensibility. The work leveraged Java development skills and object-oriented design principles, with an emphasis on clean refactoring practices. No bugs were addressed during this period, as the primary focus was on feature development and architectural improvements to support more flexible configuration management.
