Worked on the IBM/velox repository to address C++20 compatibility issues by resolving operator overload ambiguity in ComplexViewTypes. Focused on stabilizing builds and improving correctness in query processing by ensuring both parameters in comparison operators are const references to the derived type. This technical approach reduced the risk of incorrect overload resolution and enhanced reliability across C++20 environments. The work involved in-depth C++ development and software engineering practices, with careful alignment of documentation and comments to the related issue. No new features were added during this period, but the targeted bug fix contributed to more robust and maintainable code in Velox.
