Summary
👤
Senior🎓
Top SchoolTyler Han is the CTO and co-founder leading Voiceflow’s engineering organization, where he blends product vision with hands-on work on core systems like the runtime engine, visual canvas, knowledge base, and developer tooling. With nine years of experience building full-stack, cloud-native platforms (React/Node/TypeScript, Kubernetes), he has helped secure $35M in funding from top investors while keeping an active role as principal engineer and code reviewer. He has a background in rigorous CS and AI study at University of Toronto and Stanford, and early experience contributing backend and test automation work to the MarkUs academic project. Tyler’s GitHub is a candid “graveyard” of side projects—evidence of a tinkerer who prefers building privately while shipping production-grade systems publicly. He focuses on democratizing AI agent creation through collaborative conversational design, marrying developer ergonomics with scalable infrastructure. Based in Toronto, he combines startup leadership with deep technical curiosity and a preference for shipping over showcasing.
