Over a two-month period, contributed targeted engineering work to the emsec/hal and radareorg/radare2 repositories, focusing on build stability and packaging reliability. Addressed breaking changes in the Bitwuzla API for emsec/hal by updating the boolean function solver integration, parser instantiation, and error handling, ensuring continued compatibility and uninterrupted CI builds. For radareorg/radare2, resolved a shared library installation issue by implementing version-aware dynamic linkage on Linux, reducing runtime errors and improving packaging consistency. Leveraged expertise in C++, build system configuration, and API integration to deliver robust solutions that enhanced maintainability and supported ongoing development across both projects.
