Worked on the hiero-ledger/hiero-sdk-java and hiero-ledger/hiero-sdk-cpp repositories, delivering targeted improvements to code quality, maintainability, and developer experience. Focused on backend development using C++, Java, and JavaScript, the work included refactoring Java SDK imports for clarity and introducing a predefined skill hierarchy in C++ to improve issue triage accuracy. Enhanced the C++ SDK by implementing an equality operator for HbarTransfer, supporting more robust transfer workflows and easier testing. Additional contributions involved correcting documentation for non-fungible token operations and improving code readability, demonstrating a commitment to clean code, object-oriented programming, and comprehensive unit testing practices.
