About LiveDeFi

Smart Contract Engineer and DeFi Architect with 6+ years building production-grade, security-hardened, yield-oriented smart contract systems across EVM and other chains. Specialized in vault strategies, automated yield aggregation, on-chain execution pipelines, protocol risk modeling, and gas-optimized Solidity architecture. Experienced designing and shipping upgradeable contract systems, cross-protocol integrations, economic incentive mechanisms, and multi-layer governance frameworks.

Areas of Expertise

  • 🔗 Blockchain & Web3: EVM, Solana, NFTs, DAOs, smart contracts, staking, account abstraction (EIP-4337), smart wallets, DeFi primitives, secure DApps.
  • 🛡 Cybersecurity: Honeypots, threat detection, secure smart contract patterns.
