Chen Fan

I’m a Senior Full Stack AI Engineer with 10+ years of experience building production web platforms, backend APIs, data workflows, AI-integrated applications, and decision-support systems across healthcare and fintech.

At Amazon, I build healthcare-focused full-stack AI systems for document intelligence, retrieval, and privacy-aware workflow automation. I designed LLM/RAG pipelines end to end—ingestion, chunking, embeddings, vector search, grounded generation, structured outputs, and response validation—and integrated them with backend services, databases, dashboards, automation layers, and secure APIs.

I also develop agentic, multi-step healthcare workflows with retrieval, data lookup, validation, structured reasoning, recommendation logic, exception handling, escalation, and human-in-the-loop review. I’ve built predictive ML and analytics workflows using Python, SQL, Pandas, Scikit-learn, and deep learning frameworks to support segmentation, risk analysis, ranking, operational measurement, and business performance tracking.

Previously at Credit Suisse, I delivered production-oriented fintech AI and ML platforms for risk analytics and regulated decision support, including explainable AI, anomaly detection, and document intelligence with audit-friendly reporting. Earlier, as a co-founder at Dough Pack Co., I built and operated a peer-to-peer student lending platform, owning backend services, data models, lending logic, risk decision support, and reliability-focused workflows.
