Rockstar🎓
Top SchoolAllen Lin is a Full Stack Software Engineer with 10 years of experience specializing in protocol and smart contract development, particularly Solidity, alongside backend and frontend systems in JS/TS and Python. He was a core protocol engineer at Uniswap Labs, helped build UniswapX and contributed to V4, and previously founded and led engineering at genie.xyz where he architected NFT marketplace contracts and integrations later acquired by Uniswap. His work spans high-performance DeFi and NFT routing—contributing notably to Uniswap's Universal Router by adding multi-protocol support and gas-optimized integration tests. Before crypto, he built production-grade data and quant systems for asset managers, combining financial modeling, ETL, and web services. Known on GitHub/Twitter as @AzFlin, he blends "farmer, degen & dev" culture with rigorous engineering, often surfacing non-obvious protocol-level optimizations that improve composability and gas efficiency.
