I build reliable, scalable systems for fintech, compliance, Web2/Web3. 25+ years leading engineering in regulated payments and blockchain.

I work as a CTO and Consulting Architect. I solve hard problems in money movement, compliance, data integrity, and high-volume SaaS, often inside messy legacy systems or complex blockchain environments.
