PROFILE
Ryan A Rivera
Ricardo Rivera developed and maintained core data acquisition and hardware integration features for the Mu2e/otsdaq-mu2e repository, focusing on embedded systems and real-time event building. He engineered robust configuration and monitoring workflows, automated hardware programming and testing, and enhanced data integrity through UID-based file management and SQL input sanitization. Using C++, Shell scripting, and CMake, Ricardo refactored interfaces for maintainability, standardized logging and error handling, and improved system observability with visualization tools like Plotly and ROOT. His work emphasized reliability, code quality, and operational clarity, delivering production-ready solutions that streamlined hardware-software integration and reduced manual intervention across the Mu2e stack.

Aug 1, 2025Summary for 2025-08 (Mu2e/otsdaq-mu2e): Delivered robust, production-ready enhancements to support timing studies and system stability. Key features include ROC Timing Paddles Interface enhancements with improved error handling and status reporting in CFO and DTC front-ends, plus Plotly-based checkpoint visualization to support real-time progress tracking. Major bugs fixed include a PCIe reset script bug fix that now terminates boardreader processes to prevent resource conflicts and ensure a clean state after resets. Code quality improvements were made through a comprehensive clang-format cleanup across multiple C++ files, enhancing readability and maintainability. Overall, these efforts result in higher reliability for timing studies, reduced downtime during resets, and a clearer maintenance path for the codebase. Technologies demonstrated include front-end robustness, data visualization with Plotly, process management during hardware resets, and C++ code quality practices.
