Summary
👤
Senior🎓
Top SchoolCong Chen is a founding engineer with nine years of experience building AI-powered systems, currently leading development of personalized educational products in San Francisco. He blends research-grade machine learning (NLP, computer vision, reinforcement learning) with pragmatic engineering—shipping Langgraph-based agentic workflows, Streamlit UIs with OIDC, and MongoDB-backed personalization at Fastlearn.ai. Previously at Google he deployed low-latency TensorFlow pipelines that caught millions of Play Store spam requests daily while materially improving recall and throughput. His background includes high-impact scientific software at Lawrence Livermore where he trained U-Nets to 95% Dice scores and scaled signal compositing runtimes 18x, demonstrating both model and systems chops. Equally comfortable mentoring teams or working independently, he pairs a Stanford AI certificate and UC Berkeley CS/math degree with a knack for turning research prototypes into production-grade, cost- and time-saving solutions. An uncommon strength is his track record of aligning ML development tightly with business goals to cut content creation time and operational cost.
