Keerthna Ramachandran refactored the SensorChip document schema in the Benchling-Open-Source/allotropy repository, focusing on improving data modeling and measurement workflow extensibility. She reorganized the SensorChip hierarchy within the Binding Affinity Analyzer schema, added lot number and custom fields for enhanced traceability, and standardized Nanomolar unit representation to ensure consistent analytics. Using Python and schema refactoring techniques, Keerthna adjusted the placement of SensorChip within the MeasurementDocument, addressing data quality and downstream processing needs. Her work, delivered through disciplined git collaboration, provided a foundation for more reliable reporting and analytics, though it did not involve direct bug fixes during this period.
