Worked on SerenityOS/serenity to deliver a robust implementation of the posix_spawn system call, enhancing process creation by introducing a new sys$posix_spawn kernel path and optimizing performance when file actions or spawn attributes are unused. Developed a C++ wrapper in the C library to ensure user-space compatibility and added comprehensive kernel tests to validate correct behavior, including spawning standard binaries. Addressed a reliability issue in execve by restoring the calling process’s address space with a ScopeGuard, improving memory management and process stability. This work strengthened kernel and user-space API support, leveraging skills in C++, kernel development, and system programming.
