Worked on the coturn/coturn repository to deliver a deployment-hardening feature by implementing an OAuth support compile-time toggle. This addition allowed OAuth-related code paths to be conditionally excluded from builds using preprocessor directives, supporting both OAuth-enabled and OAuth-disabled configurations. The approach leveraged C programming and conditional compilation techniques to streamline the build system configuration, resulting in leaner binaries and a reduced attack surface. By validating both build modes, the work enabled greater deployment flexibility and aligned with security and release engineering objectives. The contribution focused on practical maintainability and adaptability for diverse deployment requirements within the coturn/coturn project.
