Senior Solidity Engineer

Experienced Web3 and DeFi engineer with a strong background in smart contract development, automated liquidity management,
and cross-chain interoperability. Currently leading the development and maintenance of vault-based ALM systems at Mellow
Protocol, with prior experience building performance-optimized DeFi infrastructure and smart routers. Skilled in Solidity, Foundry,
and off-chain integrations using Python and Ethers.js, with deep knowledge of Ethereum, L2s, and Uniswap V3/4 internals.
In parallel, independently researching and building high-frequency liquidity management bots and arbitrage strategies across DEXs
and chains, with a focus on non-trivial routing and latency-optimized execution.
Earlier in my career, I held senior roles in C++ and computational mechanics, including a long academic track record in numerical
methods and high-performance solvers, which now strengthens my approach to protocol-level engineering and on-chain
optimizations.
