Rockstar🎓
Top SchoolMarissa Posner is a product-focused AI/ML and Web3 engineer with 7 years of experience building developer-first blockchain products and data-driven systems from New York. She has led technical strategy as Co-Founder & CTO of two startups—Gold, a Layer 3 social gaming platform that sold $400K of in-game assets, and Sugarcane, a collaborative DeFi product—and currently drives product and developer relations for Ethereum Foundation’s Account & Chain Abstraction team. Her background as a data scientist at Teampay surfaces in rigorous analytics, forecasting, and production ETL systems, while earlier roles demonstrate a flair for community-building and growth from founding a fitness brand to competing as a professional fencer. Equally comfortable in code and product strategy, she combines hands-on ML and backend work with developer ecosystem advocacy, and contributes to Web3 tooling through projects at eth-infinitism. Ambitious about impact, she’s on a declared mission to positively affect a billion lives by building native blockchain experiences that scale.
