Web3 backend & smart contract engineer with strong hands-on experience in Go and Solidity.  

I focus on building production-ready systems across on-chain and off-chain layers, including smart contracts, backend services, and data pipelines. I have experience developing mainnet Solidity contracts (escrow, vesting), Go-based backend services, and transaction monitoring/execution systems for exchange and DeFi scenarios.  

My background includes order lifecycle design, state machines, concurrency handling, Redis/MySQL consistency, and Ethereum transaction workflows. I prefer async, code-driven collaboration and enjoy working on technically challenging Web3 infrastructure and backend systems.
