I build and break EVM / Solana / TON systems for a living. Core protocol engineering at Rango Exchange by day — diamond architectures, cross-chain bridges, account abstraction. Off the clock: competitive audits, ZK research, and AI tooling aimed at the grunt work of Web3 dev.
about
Security-first protocol engineer working across EVM, Solana, and TON. Core expertise in upgradeable architectures (Diamond Proxy), cross-chain messaging, ERC-4337 / 7702 account abstraction, and protocol security — the kind of production DeFi infrastructure where a single bug costs nine figures.
Track record: $100M+ in transaction volume routed through contracts I've written, 25+ high-impact audits across Code4rena, Sherlock, Cantina, and CodeHawks (#3 on CodeHawks First Flights, 75+ vulnerabilities), and a $1,000 disclosure bounty from LI.FI. I ship fast, then spend the next week trying to break what I shipped.
