Senior🎓
Top SchoolChris Cooper is a founder and Principal AI Engineer with 15 years of experience building production-grade distributed systems and consumer products, currently shipping an AI-native iOS app that personalizes thousands of Mandarin stories. He combines hands-on system architecture—from FastAPI backends and iOS clients to Postgres + Pinecone hybrid search—with MLOps, observability, and cost modeling to move LLM prototypes into scalable, monitored services. Chris has repeatedly led founding-engineer efforts to turn research-y LLM workflows into customer-facing features, including an AI sales research pipeline that processed tens of thousands of pages daily. He’s equally at home improving legacy risk platforms at Stripe and mentoring engineers, and has been recognized as a code approver there for quality and rigor. A software generalist by training, he pairs pragmatic product instincts with deep implementation skills in prompt chains, RAG, and production vector search. Based in Old Toronto, he brings entrepreneurial grit—having launched games and campus tools—plus a knack for shipping complete end-to-end solutions.
