Co-founder & CTO. I turn cryptography into products — DeFi lending at scale on Bitcoin, and now a ZK layer that lets enterprises use AI without their data ever leaving the building.
Somewhere between "this proof is mathematically elegant" and "does it run in production?" is where I live.
Zemtik Rust · stealth → shipping
Here's the uncomfortable truth: right now, someone at a bank or law firm is pasting their client's financial data into ChatGPT. Their CISO knows. Nobody has a fix that doesn't also kill productivity.
Zemtik is that fix. The sensitive database never leaves the company's servers. We process it locally, generate a zero-knowledge proof of the answer, and send only the proof to the AI. The model reasons correctly. The data stays home.
ZK selective disclosure. Built in Rust. For people who handle real money.

Tropykus Finance Solidity · protocol in production
Co-founded it. Built the protocol. Grew it to $18.8M+ deployed across five countries on Bitcoin/RSK. DeFi lending for people banks ignored — Colombia, Argentina, Venezuela, Mexico, Peru.
Under the hood: smart contracts, worker infrastructure, a full SDK, real-time multisig treasury monitoring, and everything else that makes a DeFi protocol not fall over at 3am.

- ETH KIPU instructor — writing ZK circuits by day, teaching them to LATAM engineers by night
- Career path went: oil rigs (Schlumberger) → cannabis traceability on-chain (Cannvest) → DeFi for the underbanked (Tropykus) → ZK middleware for enterprise AI (Zemtik). Not a straight line. Never boring.
