Rockstar🎓
Top SchoolSean Chen is a Full Stack Trainer and developer advocate with 12 years of experience building and improving full-stack systems, developer experiences, and curricula. He has practical expertise across Python, JavaScript, C, and Rust, contributing to production projects and OSS—most notably adding parsing logic and tests to the Informal Systems hermes relayer. Sean combines hands-on engineering (front-end React work, backend C servers, auth flows) with strong QA and test automation instincts, often tightening test coverage and refactoring legacy code. As a former developer relations lead he scaled onboarding and documentation with AI-powered pipelines that cut doc maintenance time threefold and helped grow community engagement. He also brings classroom experience from Lambda School and curriculum design for AI-native engineers, blending pedagogy with pragmatic engineering. Based in Chicago, he’s equally comfortable shipping features, hardening tests, and turning complex systems into teachable, repeatable workflows.
