Lead Smart Contract Engineer
Fullstack engineer with 6 years of experience. Wrote Smart Contracts for multiple audited projects. I build backend services mostly in Node.js, used Rust and Go, and
frontends in React with TypeScript. My domain is Web3:
lending protocols, exchange systems and
cross-chain settlement. The smart contracts I wrote passed external security audits. I use Claude
Code, Cursor and Copilot every day for code, review and test generation. As tech lead I review
architecture, supervise audits and mentor backend, DevOps and frontend engineers. I write my
decisions as documents.
