Summary

  • 12+ years of full-stack engineering across web, mobile and decentralized systems; 9+ years in blockchain, crypto and DeFi.
  • Originated the concepts behind Dash’s DML, SML, LLMQs and ChainLocks; the wider engineering team formalized the DIPs and delivered the implementations. Named co-inventor on published US patent application US20220108285A1 for the underlying deterministic-masternode and quorum architecture; ChainLocks itself is outside the application. The resulting architecture has protected blockchain networks representing billions in value.
  • Shipped 20+ production smart contracts (ERC-20/721/1155/4626, vote-escrow governance, treasury, time-locks) and invented a crypto-RWA index on a ~$100M-TVL protocol.
  • Led and hired engineering teams; co-founder and head-of-engineering experience with strong product ownership and architecture leadership.
  • Security-conscious, adversarial-environment hardened: smart-contract audits, operational security, 0-day crisis response.
  • Users' advocate by method: builds as a user first, and translates deep technical systems into plain language for non-technical stakeholders, from investors and boards to consulting clients and conference audiences.
  • Public speaker and writer: Money20/20, conferences, podcasts and interviews.
