Top SchoolErick Friis is a founding engineer and MIT-trained software engineer with 11 years of experience building systems at the intersection of machine intelligence, product prototyping, and user-centered design. He has shipped production and research-driven work across startups and established teams—from Instabase’s Machine Intelligence platform to contributions as a full‑stack developer on the popular LangChain JS project. Erick combines hands-on engineering (backend, integration tests, and node-only features) with product intuition developed prototyping smart speakers, social robots, and anomaly detection tools. He also has a history of teaching and mentoring at MIT and a founder’s mentality from co-founding Chestnut and running a student tech repair business. Based in San Francisco, he balances technical depth with practical UX research and a penchant for two-wheeled and ski-bound adventures.
