Web3 Developer

As a blockchain development engineer with 2 years of hands-on experience, I've specialized in building robust Web3 solutions, focusing on smart contracts, DeFi protocols, and automated trading systems. My background includes a Bachelor's in Network Engineering from Hubei Polytechnic University, where I honed my computer science fundamentals, followed by roles as a Network Engineer and Operations Engineer, managing enterprise networks for high-concurrency environments.

Key highlights from my work: I led the architecture and development of AutoTransaction-Nextgen, an event-driven multi-chain market making and automated trading runtime using Node.js, ethers.js, and Sui, incorporating AI-assisted iterations for efficiency. I've deployed Solidity contracts on Ethereum testnets (ERC-20/721/1155 standards), built blockchain interaction tools with Wagmi and Remix integrations, and explored Rust for IPFS-related utilities. Proficient in tools like Hardhat, Foundry, Slither, and frameworks such as ReactJS and Ethers.js, I'm passionate about DeFi, AMM, perpetual contracts, and consensus mechanisms (PoW/PoS/PBFT).

I'm seeking a Blockchain Development Engineer role, ideally in Shenzhen or remote, to contribute to innovative Web3 projects. Open to negotiating salary based on location and cost of living—let's connect if you're building the future of decentralized tech!
