Worked on foundational C++ compatibility improvements across the aws-c-http and aws-c-io repositories, focusing on safer integration and future maintainability. In aws-c-http, introduced an enum for HPACK decode types outside the struct, enabling forward declaration and laying the groundwork for C++ support in HPACK decoding. In aws-c-io, enhanced the testing utilities by adding explicit type casts from void pointers to specific struct types, improving type safety and compatibility within the C testing infrastructure. Leveraged C and low-level programming skills to coordinate these changes, which collectively reduce integration risk and prepare the codebase for broader C++ adoption in future development.
