PROFILE
Wenyuanchen1326
Worked on the HealthRex/CDSS repository, delivering clinical decision support features and data-driven analytics over five months. Developed and enhanced a FastAPI-based recommender API, integrating BigQuery for scalable clinical data retrieval and ICD-10 lookups. Implemented secure environment variable management, improved repository hygiene, and refactored data pipelines for VM migration readiness. Leveraged Python, SQL, and Jupyter Notebooks to build reproducible analytics workflows, including LLM-assisted code matching and error analysis frameworks. Focused on enabling PSB submission readiness by preparing experimental notebooks and reference datasets, while maintaining production reliability through logging cleanup and robust error handling to support ongoing clinical informatics research.

May 1, 2025May 2025 focused on security hygiene, data-layer groundwork, and extended decision-support capabilities for HealthRex/CDSS. Key achievements include: 1) Recommender API Security and Maintenance Enhancements (load API keys from environment variables; update .gitignore to exclude logs and notebook artifacts); 2) Phase 1 Recommender with BigQuery Data Layer (establish BigQuery-based data retrieval with foundational notebook and dependencies); 3) Medical Recommender API Enhancements (Antibiotics) (antibiotic susceptibility integration, structured API for clinical cases, language-model-assisted code matching, and ICD-10 lookups via BigQuery). Major bugs fixed: reduced exposure and deployment noise via environment-based keys and improved gitignore. Overall impact: stronger security posture, cleaner deployments, and a scalable data-driven foundation enabling faster feature delivery and clinical decision support. Technologies/skills demonstrated: environment variable management, Git hygiene, BigQuery integration, API design, ICD-10 lookups, and NLP-assisted code matching.
