PROFILE

Simoncjliao

Over nine months, this developer enhanced the EasyEyes suite by building and refining calibration, data collection, and experiment management features across the threshold, threshold-scientist, and website repositories. They implemented robust audio calibration workflows, improved UI consistency, and introduced metadata-driven data handling to increase reliability and traceability. Using JavaScript, TypeScript, and CSS, they integrated API-based date tracking, streamlined file parsing, and upgraded sound analysis methods. Their work addressed both user-facing and backend challenges, such as early data persistence and cross-repo configuration alignment, resulting in more accurate calibration, reduced data loss, and maintainable code that supports ongoing research and experimentation.
