Developed and delivered two specialized data recognizers for the microsoft/presidio repository, focusing on Philippine identifiers. Built the Philippine Mobile Number Recognizer to extract both international and national formats, aligning with ITU-T E.164 standards, and implemented comprehensive unit tests and documentation updates to ensure reliability and maintainability. Subsequently, created the Philippine UMID recognizer using Python and Regex, supporting dashed and plain 12-digit formats with context-aware validation for accurate detection. Both features included robust test coverage, changelog updates, and integration into system configuration, demonstrating a methodical approach to full stack development, testing, and documentation within a compliance-focused data extraction framework.
In 2026-07, delivered the Philippine UMID recognizer for the Presidio analyzer (PH_UMID), enabling automatic detection of Philippine UMID numbers in documents to enhance compliance and data extraction. Implemented regex-based matching for both dashed and plain 12-digit formats, plus context-aware validation, and registered the recognizer in system configuration with comprehensive unit tests and documentation updates.
