Gavin Crone engineered modular backend systems for the DUNE-DAQ stack, focusing on configuration, resource management, and data acquisition workflows across the appmodel and daqconf repositories. He refactored core APIs and standardized resource handling using C++ and Python, introducing contract-based data retrieval and schema-driven configuration to improve maintainability and integration reliability. His work included overhauling module generation interfaces, unifying data access layers, and implementing resource visualization tools for debugging and QA. By aligning codebases with evolving schema models and modernizing configuration flows, Gavin reduced integration risk and technical debt, enabling faster onboarding and more robust, scalable system evolution.

October 2025 performance summary: Delivered a targeted refactor to standardize data access across the DUNE-DAQ stack by adopting a unified data access layer in daqconf. This involved migrating usage to confmodel_dal and updating imports and function calls across multiple modules to reflect the unified data access approach, reducing divergence and easing future data-layer evolution. In parallel, ensured system stability with Connectivity Server Renaming Compatibility in daqsystemtest by aligning configurations to the renamed connectivity server; this maintained operability without introducing code changes. Impact and value: Strengthened data access consistency, reduced maintenance risk, and improved integration reliability with external services. The changes enable faster onboarding of new components and safer refactors of the data layer, supporting longer-term scalability and performance improvements. Technologies/skills demonstrated: Python refactoring, API/data-layer modernization, cross-repo coordination, configuration management, and disciplined version-control practices.
