Worked on modernizing the build system for the JCSDA-internal/ufo-data repository by integrating ecbuild with CMake, enabling robust package discovery and streamlined downstream consumption. Updated the CMakeLists.txt configuration, renamed the project to ufo-data, and ensured proper installation and find_package-based discovery to align with internal build standards. Later, refactored and modularized observation file validation by relocating validation logic from ufo-data into the ufo project, improving maintainability and reducing code duplication. Focused on modular programming and build system configuration, these contributions enhanced reproducibility, onboarding, and code reuse across components, leveraging CMake and software development best practices throughout the process.
