Experienced Web3 developer specializing in Solidity smart contracts for Ethereum, Polygon, BSC, and other EVM chains. I build secure, gas-efficient contracts for DeFi protocols, NFTs (ERC-721/1155), tokens (ERC-20), DAOs, staking/farming systems, and full dApps.
What I deliver:

Custom smart contract development from scratch
Gas optimization (reduce fees by 20-50%)
Security audits & best practices (reentrancy, overflow checks, OpenZeppelin libraries)
Integration with frontends (Web3.js, ethers.js, React/Vue)
Testing (Hardhat, Foundry, unit/integration tests)
Deployment & verification on explorers

Why choose me?

100% focus on security – no rugs or exploits
