Worked on the apache/guacamole-server repository to enhance code compliance and maintainability by focusing on C standards and modern best practices. Addressed issues raised in GUACAMOLE-2136 by adding 'void' to parameter-less function declarations and removing unused variables in the C codebase, which improved portability and reduced compiler warnings. Ensured robust builds across GCC and Clang toolchains by enforcing strict compilation flags, thereby preventing future regressions. The work centered on C programming, code compliance, and software maintenance, resulting in cleaner, more maintainable code that supports long-term contributions and traceability within the project, while aligning with evolving C language standards.
