During this period, work focused on delivering two features across the hiero-ledger repositories, emphasizing build system modernization and improved type safety. In hiero-sdk-cpp, the build process was upgraded by raising the CMake minimum version to 4.3, which enabled access to newer CMake features and policies, enhancing reliability and future compatibility for downstream projects. Meanwhile, in hiero-sdk-js, the topic modules were refactored to use a generic Client type parameterized by Channel and MirrorChannel, increasing type safety and code clarity. The work demonstrated proficiency in CMake, JavaScript, and TypeScript, with an emphasis on maintainable build systems and robust refactoring.
