Sergi Asensio
Developed and integrated a Spanish Passport recognizer into the microsoft/presidio repository, expanding the platform’s ability to identify and validate Spanish identity documents for onboarding workflows. Leveraged Python and regular expressions to implement robust pattern recognition, ensuring accurate parsing and compliance with document standards. Enhanced documentation and unit tests to reflect the new feature, improving maintainability and reducing the risk of misclassification. Refined existing code by correcting formatting in Spanish NIF/NIE descriptions, updating regex flags, and reorganizing import statements for better code style adherence. Collaborated cross-functionally and maintained clear version control practices throughout the development and release process.
