Worked on reorganizing the equinor/fmu-dataio codebase to improve maintainability and collaboration. Consolidated common data models into a dedicated directory, updating schema references and version numbers across metadata files to align with the new structure. This restructuring, implemented using Python and YAML, clarified the project’s architecture and reduced coupling between components. The changes laid a foundation for easier onboarding and future automation by making updates and refactoring more straightforward. Focused on data modeling and software architecture, the work addressed cross-team coordination challenges and set the stage for more reliable feature delivery without introducing new bugs during the development period.
