Worked on expanding data transformation capabilities within the google-research/kauldron repository, focusing on the Kauldron Grain Map Pipelines. Delivered FlatMap Transform support by implementing FlatMapTransform handling in the internal _apply_transform method, which produces a FlatMapMapDataset. This addition enables FlatMap-based data transformations, allowing for more flexible and complex pipeline workflows. The approach simplified downstream analytics and positioned the project to support richer transformation patterns with minimal code changes. Utilized Python for both pipeline development and data engineering tasks, emphasizing maintainable code and robust dataset construction. No major bugs were addressed during this period, with efforts concentrated on feature delivery.
