    Mary successfully delivered the required bug fixes, resolving tricky voice playback interruptions and auto-titling flows across both app modes. She has a strong understanding of Flutter and backend API integration, and brought the build to a stable release state.

    Clear communication throughout, fair when I raised concerns, and the end result held up. A couple of issues came up during testing and Mary was quick to diagnose and fix each one properly. Highly recommend.
