Hands-on CTO / Full-Stack Blockchain Engineer | Rust/CosmWasm (IBC) + Solidity/EVM | Web3/DeFi (DEX, Lending, Perps) | AI/LLM integrations
I’m a blockchain engineer / hands-on CTO with 15+ years of software experience and since 2021 focused full-time on Web3/DeFi.
I help startups ship production-grade products end-to-end: smart contracts (CosmWasm/Rust/IBC and EVM/Solidity), backend services (APIs, indexing/sync, background jobs), CI/CD, cloud infrastructure, and I can jump into the frontend when needed.
Things I’ve built: DEX, NFT marketplace, on-chain name service, cross-chain token implementations, staking utilities, and lending/borrowing products (incl. perps features).
Tech: Rust, CosmWasm, Solidity, TypeScript, NestJS, React/Next.js, Postgres/MySQL, Redis, WebSockets, GitHub Actions/CI, AWS/Azure/Vercel/Railway.
Recently, I’ve also been integrating AI/LLM features into products (APIs, automations, agent workflows).
If you need someone who can own the full stack and lead a small team, I’m your guy.
