I work on financial and crypto systems where failures have real consequences.

Over the past 15 years, my work has focused on:

• trading and financial infrastructure
• blockchain protocols and token models
• systems that handle money, risk, and irreversible operations
• explicit rules and invariants instead of ad-hoc business logic

In recent roles, I worked with small engineering teams while retaining primary technical ownership. My responsibilities included system design, key implementation decisions, and production behavior.

• dxs-consigliere

I’m open to CTO or principal architect roles in early-stage crypto / fintech teams where system design and risk modeling are central.
