Ziyang John worked on the ntu-pear/PEAR_patient_service and PEAR_WebFE repositories, building scalable patient data management features with a focus on dementia, mobility, and image handling. He designed and implemented RESTful APIs and CRUD operations using Python, FastAPI, and SQLAlchemy, ensuring robust data integrity and auditability. His work included Cloudinary integration for image uploads, advanced logging for observability, and frontend enhancements in React and TypeScript to support account logs and authentication flows. By refining deployment pipelines with Docker and Kubernetes, Ziyang enabled reliable CI/CD and environment parity, delivering maintainable, testable systems that support analytics, compliance, and future feature growth.
May 2025 performance summary for ntu-pear/PEAR_patient_service. Focused on improving observability and auditability of patient mobility updates. Delivered a feature enhancement to audit logging and ensured complete data capture for traceability, including PatientID, across CRUD operations. The work improves compliance readiness, debugging efficiency, and data lineage without impacting core functionality.

February 2025 performance summary focusing on business value and technical execution across two repositories (PEAR_patient_service and PEAR_WebFE). Key features delivered include a patient image management prototype with Cloudinary integration and CRUD scaffolding, and a frontend Account Logs page for auditing. Major infrastructure and data integrity improvements include CI/CD and deployment refinements with Cloudinary environment variable handling, Docker/Kubernetes tweaks, and resource scaling optimizations, plus a safeguard enforcing isDeleted checks to prevent updates to soft-deleted records. Additionally, the Account Logs UI was implemented with routing, mock data, search, detail view, and pagination for improved observability. Unit testing for image upload and boundary checks began but was not completed; groundwork for data models and payload schemas completed to support scalable media features.

December 2024 monthly summary for ntu-pear/PEAR_patient_service. Focused on establishing a scalable dementia data management capability to support patient care, governance, and analytics. Delivered foundational data model and REST APIs for dementia lists and mappings, including CRUD operations, database schema updates, and routing. Extended the dementia mapping functionality with an endpoint to fetch all assigned dementias across patients and refined create/update logic to properly handle isDeleted flags and timestamps. These efforts deliver data integrity, cross-patient visibility, and a solid foundation for future analytics.
