Developed and delivered Seekr Mobile App Detection for both iOS and Android within the matomo-org/device-detector repository, focusing on enhancing user agent parsing and traffic categorization. The work involved updating YAML-based fixtures and implementing new regex patterns to accurately identify Seekr app usage, thereby improving device attribution and analytics segmentation. Demonstrated expertise in device detection, mobile app identification, and user agent parsing, with all changes consolidated into a single, well-documented commit for clear traceability. No major bugs were addressed during this period, and the contribution was scoped to a targeted feature that enables more precise client insights for Seekr-related traffic.
