Summary
🤩
Rockstar🎓
Top SchoolTracy Shen is a Staff ML Engineer with 11 years of broad data and ML experience and seven years focused on applied ML/AI, specializing in LLM/VLM development, finetuning, deployment, and monitoring. She has led production projects that materially improved RAG systems and table extraction—finetuning Qwen2VL to surpass Claude-3.5 and GPT-4o on table tasks—and authored a public Model Context Protocol (MCP) server and numerous data connectors. Tracy combines deep learning expertise (PyTorch, TensorFlow, BERT-like models) with solid MLOps skills (Docker, Kubernetes, CI/CD, SageMaker) to take models from research to reliable services. Her AI engineering spans agentic workflows (document analysis, SQL↔NLP, Q&A) and model evaluation tooling, with a track record of reducing retrieval failures and boosting recall in production. Multilingual and analytically versatile, she also brings SQL/warehouse experience (Snowflake, BigQuery, Teradata), BI visualization skills, and hands-on API and platform development. Outside work she’s a triathlete and rock climber, a detail that mirrors her endurance for long, complex model tuning and system-level problem solving.
