Engineering leader with 18 years in engineering, 10 across payments, fintech, and crypto. Built financial infrastructure at Coinbase and Nium that processes real money at scale — not prototypes.

At Coinbase: led the Financial Platforms & Tax org. Shipped the unified ledger platform (10B+ records/month, 350+ fund flows), built IRS digital asset reporting for 70M+ users (1099-DA, CARF/DAC8), and drove AI-assisted development with 80% of PRs authored via Claude — with compliance guardrails in production.

At Nium: Director of Engineering. Built the cross-border payments and reconciliation platform from zero — 99.999% uptime, 95% auto-reconciliation across 600+ bank accounts and 100+ currencies. Scaled the org from 10 to 40+ engineers with 3 promotions in 7 years.

Looking for Director or VP Engineering roles in crypto infrastructure, payments, ledger systems, or compliance platforms. Open to remote (US/UK/EU overlap) or relocation with sponsorship.
