I build AI, systems, hardware, sometimes rockets.

Now building Entropy, the infrastructure layer for emotional intelligence.


Dropped out at 19. Built my first company.

Founded a blockchain intelligence company.

Built investigation and compliance tools for government agencies — ML-powered transaction tracing, entity clustering, and fraud detection across multiple chains. Helped partners detect and prevent illicit financial activity on-chain. 100k users, $500k ARR. Acquired. Full investor exit.

Founding Ecosystem Lead at Scroll — helped scale it to a $1.8B valuation.

Ran grants, hackathons, and developer programs across 10+ countries. Worked hands-on with builders across 100+ protocols and thousands of developers, taking the ecosystem from early zero to a live production network.

Founded Entropy, a foundation lab for emotionally intelligent AI.

Self-funded $1M and spent three years building a local-first stack across production-grade language, speech, memory, and behavior systems, plus a low-latency on-device runtime with zero inference cost. I lead product, operations, community, agent architecture, and control systems, including the Cognitive Tree and AI Narrative Director.
