Worked on the equinor/semeio repository to address a targeted data quality issue in RFT trajectory handling. Focused on backend development and data engineering, the work involved implementing a robust fix for scenarios where RFT data was missing by returning None instead of an empty list in the gendata_rft_populate_trajectory_points function. This approach improved type hinting and ensured greater consistency in handling missing data, thereby strengthening data contracts and reducing downstream failures. Using Python, the developer enhanced the reliability of the data pipeline, contributing to more predictable and maintainable data flows without introducing new features during the period.
