Worked on the google/skia repository to address a critical DLL boundary issue affecting public API exposure. Focused on C++ development and DLL management, the work involved exporting SkFontMgr::Request methods to resolve linker errors encountered by component-built callers accessing nested type members across DLL boundaries. The approach maintained exact behavior and ABI, ensuring no changes to the public API surface beyond necessary export annotations. Collaboration included code reviews and coordination with cross-team stakeholders to align on Windows and Clang export semantics. This fix improved downstream integration stability, reduced build failures, and preserved performance, demonstrating depth in API design and cross-module compatibility.
