👤
Senior🎓
Top SchoolJohn Gribbin is a co-founder and hands-on engineering leader with 8 years building production software across crypto, fintech, and media. He leads Clams, shipping Bitcoin accounting infrastructure (CLI and REST API as a single Rust binary) while owning product, go-to-market, content, SEO, and business development. Previously he scaled infrastructure and built the first crypto-native engineering team at 21.co/21Shares, then led an AI-powered product that fused LLMs with live blockchain data. His core stack is TypeScript/Node.js with Rust in the mix, and he runs AI-native development workflows using agentic tools like Claude Code and Codex. Comfortable owning projects end-to-end, he prefers autonomous roles or select contracts focused on Bitcoin, TypeScript/Node, or AI-native systems. A practical tinkerer by background, he bridges deep protocol knowledge with commercial product instincts.
