About this Gig
I build smart contracts and decentralized applications on Ethereum and EVM-compatible chains. If you need DeFi protocols, NFT platforms, or Web3 integration, I can help you build it correctly.
What I've built:
I developed a full DeFi platform with liquidity pools, token swapping, staking rewards, and price oracles. I've created ERC-20 tokens, ERC-721 NFTs, and integrated Web3 wallets using RainbowKit and wagmi. My dApps include frontend interfaces with Next.js and smart contract deployment with Hardhat.
What you get:
- Secure, audited-ready smart contracts
- Full testing suite (unit tests, integration tests)
- Gas-optimized code
- Frontend integration (React, Next.js)
- Web3 wallet connection (MetaMask, WalletConnect)
- Deployment to testnet and mainnet
- Complete documentation
- Source code on GitHub
Technologies: Solidity, Hardhat, Ethers.js, Web3.js, React, Next.js, TypeScript, OpenZeppelin OpenZeppelin, RainbowKit, wagmi, IPFS, The Graph.
