In July 2025, Juan Besa focused on cross-repository code quality improvements by standardizing code style enforcement in the facebook/fbthrift and facebook/hermes repositories. He migrated both codebases to use the readability-braces-around-statements static analysis check, replacing previous style rules to ensure consistent formatting and improved readability. Working primarily in C++ and leveraging static code analysis tools, Juan’s changes enabled more reliable automated checks and streamlined the code review process. While no major bugs were addressed during this period, his work laid the foundation for easier onboarding, reduced downstream defects, and better maintainability across both projects through unified code standards.
