During August 2025, Ai Zhou refactored the stuffer module in the aws/s2n-tls repository to standardize function naming, focusing on improving code readability and long-term maintainability. Working in C, Ai Zhou applied software refactoring and maintenance skills to rename functions without altering their behavior, ensuring API compatibility while making the codebase easier to review and extend. This targeted change addressed the risk of misnaming and reduced future maintenance overhead, supporting faster onboarding and cleaner diffs for contributors. The work demonstrated a methodical approach to code quality, emphasizing clarity and consistency in a critical component of the TLS library’s infrastructure.
