Javier Campos

Worked on the Mu2e/otsdaq-mu2e repository, focusing on maintainability, data access, and code quality over a two-month period. Applied C++ and SQL skills to refactor core components, including a safety-oriented update to the ConfigurationManager and improvements to database interaction methods. Enhanced error handling and standardized API naming for greater clarity and reliability. Removed obsolete debugging utilities to streamline the codebase and reduce confusion. Updated run records to use SQL views, improving data accuracy and query performance. Emphasized object-oriented programming and code readability, laying a foundation for faster feature delivery and more robust, maintainable software development practices.
