I build smart contracts and AI powered blockchain tools that work in production. Secure, gas optimized, and delivered on time. BSc in Artificial Intelligence. 100% Job Success. Clients say I "get up to speed fast" and "go out of my way to deliver." I specialize in the intersection of AI and blockchain. Whether you need a Solidity contract, a DeFi mechanism, or an AI agent integrated with on chain logic, I handle it end to end. 𝗪𝗵𝗮𝘁 𝗜 𝗕𝘂𝗶𝗹𝗱: 𝗦𝗺𝗮𝗿𝘁 𝗖𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝘀 & 𝗧𝗼𝗸𝗲𝗻𝘀 ERC-20/ERC-721, custom tokenomics, staking, vesting, and access control using Solidity + OpenZeppelin + Hardhat 𝗗𝗲𝗙𝗶 𝗣𝗿𝗼𝘁𝗼𝗰𝗼𝗹𝘀 Uniswap liquidity pool integration, yield mechanics, token launches, and DEX interactions (hands on experience deploying live pool contracts) 𝗔𝗜 + 𝗕𝗹𝗼𝗰𝗸𝗰𝗵𝗮𝗶𝗻 𝗛𝘆𝗯𝗿𝗶𝗱 𝗧𝗼𝗼𝗹𝘀 Python based smart contract analyzers (AST parsing), on chain automation scripts, AI agent backends with Web3 connectivity 𝗪𝗲𝗯𝟯 𝗱𝗔𝗽𝗽 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱𝘀 React/Next.js interfaces connected to contracts via Ethers.js and Web3.js, wallet integration (MetaMask, WalletConnect) 𝗠𝘆 𝗘𝗱𝗴𝗲: Most blockchain devs don't understand AI. Most AI devs don't understand smart contracts. I studied AI formally and have shipped production Solidity, which means I can build the kind of AI integrated Web3 tools that clients increasingly need. 𝗥𝗲𝗰𝗲𝗻𝘁 𝗪𝗼𝗿𝗸 & 𝗣𝗿𝗼𝗷𝗲𝗰𝘁𝘀: → Built a Python + Solidity AST smart contract analysis tool (137 hrs, 5.0 ★ on Upwork) → Deployed Uniswap liquidity pool contracts for an ETH token launch (5.0 ★ on Upwork) → Architected a full-stack on-chain prediction market platform with custom tokenomics, leaderboard system, epoch-based rewards, and creator/trader mechanics from smart contract design through frontend → Built and shipped complete web platforms with brand systems, multi-page navigation, and bilingual UI for enterprise clients Beyond Upwork, I've been actively building in the Web3 space, designing token economies, prototyping DeFi mechanics, and developing AI integrated on chain tools. The Upwork reviews are just the tip of the iceberg. 𝗧𝗲𝗰𝗵 𝗦𝘁𝗮𝗰𝗸: Solidity, Python, JavaScript, React, Next.js, Ethers.js, Web3.js, Hardhat, OpenZeppelin, Ethereum, Polygon, BSC, IPFS Let's talk about your project. I typically respond within a few hours.
