During February 2025, Daniel Esteves enhanced the maybe-finance/maybe repository by developing a CSV import feature that supports multiple number formats and currency handling. He updated backend models and the user interface to allow users to specify regional formats during data import, ensuring accurate parsing across international locales. Using Ruby, SQL, and HTML, Daniel implemented comprehensive unit and integration tests to cover various formats and edge cases, improving data integrity and reducing manual data cleaning. His work focused on backend development, CSV parsing, and internationalization, ultimately streamlining onboarding for multi-region customers and strengthening the reliability of the import pipeline.
