Full Stack Solidity Engineer / Team Lead / Cto

I am a Senior Solidity Engineer with 7+ years of experience deploying production-ready smart contracts across Ethereum and 20+ EVM-compatible networks. My background spans DeFi, MEV, cross-chain infrastructure, and staking protocols. I’ve built lending systems (Filecoin EVM), multi-step yield strategies, optimized DEX swaps, Smart Order Routing, and high-performance MEV bots.

I specialize in secure and gas-optimized contract design, with strong expertise in Solidity, Foundry, Hardhat, TypeScript, and backend integrations. My work has been recognized with awards such as the ConsensusLab Grand Prize at Open Data Hack and 3rd place in the Encode Club’s smart contract optimization competition.

I’m looking for a long-term role at a growing company, where I can apply my skills in building reliable, safe, and scalable blockchain infrastructure, contribute to protocol design, and drive innovation in DeFi, staking, and cross-chain systems.
