What I'm looking for

I'm seeking senior blockchain roles where I can design secure, scalable DeFi protocols and smart contracts, collaborate cross-functionally, and drive measurable performance and efficiency improvements.

I am a blockchain engineer with 8+ years building DeFi protocols, AMM infrastructure, and high-volume NFT systems across Solana, Ethereum, and other EVM chains. I have driven measurable gains such as a 40% gas efficiency improvement, architected concentrated liquidity models, and delivered production-grade smart contracts in Rust and Solidity.

I design secure, scalable systems—from Anchor/Rust marketplaces and CPI-based escrow flows to ERC-20 collateral vaults and cross-chain integrations—while collaborating with product and compliance teams to ensure robust, auditable deployments and strong user experiences.
