Summary
🤩
Rockstar🎓
Top SchoolSean Kilgarriff is a Co-Founder and software engineer with a decade of experience building compliant, production-grade blockchain infrastructure from Minneapolis. He leads Urkel, the operator of the world’s first fair-pay and the only US-based compliant mining pool, and co-founded WEB3MSP to advance Web3 culture and business regionally. Sean pairs hands-on backend engineering—demonstrated by contributions to notable open-source projects like the Handshake full node and Rust metrics tooling—with product and regulatory focus to deploy hashrate as a tradable commodity on public markets. His work blends systems-level blockchain protocol improvements (RPC and node data modeling) with practical operational tooling and observability improvements. Trained in economics and computer science at Columbia, he brings both technical depth and market-aware thinking to decentralized infrastructure. An uncommon strength is his dual focus on compliance and open-source collaboration, making him effective at shipping auditable, production systems in a regulated environment.
