I'm a senior smart contract engineer with 4+ years of blockchain experience and 15+ years in distributed systems. I deliver production-ready Solidity smart contracts with security audits and gas optimization.
WHAT I CAN BUILD:
✅ DeFi protocols (AMM, lending, liquidity mining, staking)
✅ NFT marketplaces, rental platforms, and auction systems (ERC-721/1155/4907)
✅ Token standards (ERC-20, ERC-777, governance tokens)
✅ Cross-chain bridges and interoperability solutions
✅ Custom smart contracts for any EVM chain (Ethereum, BSC, Polygon, Arbitrum, Optimism)
MY EXPERTISE:
• Solidity 0.8.x + OpenZeppelin security patterns
• Smart contract auditing (Slither, Mythril, Foundry Fuzz)
• Gas optimization — reduced costs by 40-60% across projects
• EIP-712 typed data signing for gasless transactions
• 97% test coverage with Hardhat + Foundry
PROVEN RESULTS:
• DeFi protocol TPS: 3x improvement
• Cross-chain transaction latency: 200ms → 50ms (75% reduction)
• Fixed 25+ high-severity vulnerabilities (reentrancy, integer overflow)
• System uptime: 99.99%
TECH STACK:
Solidity • Hardhat • Foundry • OpenZeppelin • Web3.js • Ethers.js • Next.js • React • TypeScript
Deliverables include: source code, tests, deployment scripts, and documentation.
