Anthony D'addeo is a seasoned backend engineer with 12 years of experience building and hardening production systems, particularly in e-commerce and decentralized app infrastructure. Based in Austin, he’s contributed meaningful fixes and feature work to prominent open-source Ruby on Rails projects like Solidus and Spree, improving product and order handling across complex, multi-tenant storefronts. He also helped implement core Farcaster hub functionality—optimizing RPC, trie sync, and message handling—showing a knack for distributed systems and performance-focused refactors. Once a college football Longhorn, he brings team-first discipline to engineering and a humanistic curiosity that drives him toward ideas at the intersection of technology and the humanities. Pragmatic and detail-oriented, Anthony prefers substantive engineering work over hype (he explicitly did not launch a memecoin). He balances deep backend expertise with an appetite for maintainable, well-tested code and thoughtful technical trade-offs.
