Worked on the vlang/v repository to enhance musl libc detection, broadening compatibility across various Linux distributions. The approach involved replacing an Alpine Linux-specific check with a more general musl presence detection, which improved portability for V language builds in musl-based environments. Addressed a critical issue related to __atomic_thread_fence behavior on musl systems, ensuring correct atomic operations and increasing build reliability. Leveraged skills in compiler design, cross-platform development, and system programming, primarily using the V language. This work reduced environment-specific failures and strengthened cross-distro support, reflecting a focused effort on robust, maintainable system-level improvements within the V ecosystem.
