During November 2025, Alexandru focused on enhancing data quality within the SuadeLabs/fire repository by addressing a critical issue in the loan schema. He corrected the occupancy_rate field’s data type from string to number, ensuring accurate data representation and preventing errors in downstream financial calculations. Alexandru applied his expertise in data validation and schema design, using JSON to implement and document the change. He validated data integrity through targeted checks and maintained backward compatibility with existing analytics. The work was well-documented and traceable, reducing the risk of incorrect occupancy analytics and improving the reliability of reporting and financial processes.
