Summary
👤
Senior🎓
Top SchoolEric Stern is a founder and engineering leader with 12+ years building high-reliability systems in payments, knowledge graphs, and developer tooling. He architected and scaled Lustre’s knowledge graph and unified API to serve millions of pages and hundreds of thousands of products, and earlier built WePay’s money engine and fraud/security systems that processed billions in volume prior to acquisition by JPMorgan Chase. A hands-on manager and startup advisor, he combines CI/CD, privacy-first product thinking, and cost-conscious infrastructure moves (notably a 40% infra cost cut via a GKE migration). Eric is now building SnapAuth to make passkeys simple and breach-resistant for developers, drawing on deep payments and security experience. He’s an active open-source contributor (improving Phabricator’s arcanist CLI) and a home automator who treats user data as a liability to earn trust.
