Yahan focused on stabilizing WebAssembly build support for the nodejs/node repository, specifically addressing build failures on the riscv64 Linux architecture. By updating the v8.gyp build configuration with architecture-specific logic and conditional sources, Yahan enabled successful WebAssembly compilation on both riscv64 and x64 platforms. This work leveraged C++ and build system configuration skills to ensure that cross-platform development needs were met, reducing manual troubleshooting for future Linux architectures. The fix improved CI reliability and platform coverage, allowing broader and faster validation of cross-architecture changes. Yahan’s contribution demonstrated depth in cross-platform build engineering and careful attention to maintainability.
