Worked on the bytecodealliance/wasm-micro-runtime repository to enhance cross-platform portability by addressing a critical compatibility issue in WASM type definitions. Refactored C code to replace enums with macro-based type definitions, ensuring consistent type sizes across different platforms and reducing ABI-related risks during builds and runtime. This change stabilized embedded and server-side deployments by eliminating enum-size mismatches between WASM and host environments. Demonstrated expertise in system programming, WASM, and cross-platform development, with a focus on macro refactoring and thorough cross-platform testing. Collaborated effectively through code reviews and signed-off contributions, emphasizing code quality and reliability in a complex runtime environment.
