Alejandro contributed to the DUNE-DAQ codebase by developing and optimizing data acquisition and processing features across multiple repositories, including fdreadoutlibs and daqsystemtest. He engineered core components such as the TPCEthFrameProcessor, introducing template-based adapters, improved sequence handling, and integrated metrics collection to enhance throughput and maintainability. His work involved refactoring legacy code, standardizing terminology, and implementing MessagePack serialization for trigger data, which streamlined data flows and reduced serialization overhead. Using C++, Python, and CMake, Alejandro focused on configuration management, low-level programming, and real-time systems, delivering robust solutions that improved reliability, performance, and clarity in complex embedded environments.

October 2025: Delivered key data-path improvements across DUNE-DAQ/fdreadoutlibs and DUNE-DAQ/daqsystemtest, delivering measurable business value in data throughput, reliability, and maintainability. Achievements center on a new generic TPCEthFrameProcessor, targeted config enhancements, improved data handling, and tuned trigger primitive generation for test environments.

February 2025 monthly summary: Refactored data models and processing paths to reflect current system operation, reduce serialization overhead, and simplify maintenance across DUNE-DAQ components. Key changes include removing serialization and usage of TriggerPrimitive type and algorithm fields, and removing TPGAlgorithmClassifier and TP classification from WIBEthFrameProcessor, aligning processing with actual data flows and reducing surface area for future bugs. These changes improve data integrity, reduce payload sizes, and support easier future evolution of the trigger and frame-processing pipelines.

December 2024: Stabilized debug logging in raw_hdf5_reader within DUNE/waffles by removing an unassigned 'trig' reference. This prevents misleading debug output and potential errors, improving reliability of development and incident debugging. Implemented with a focused change (commit e2265093440094cc4ba6fa68b72cb7c478fbb25a) across the codebase, reducing noise in logs and aligning with code quality initiatives.
