Have you ever launched a blockchain or AI project that looked great on paper but fell apart in production? I've spent 8 years making sure that doesn't happen, across token launches, DeFi protocols, NFT platforms, and now AI agents and LLM-powered systems. 𝗛𝗲𝗿𝗲'𝘀 𝘄𝗵𝗮𝘁 𝘁𝗵𝗮𝘁 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝗹𝗼𝗼𝗸𝘀 𝗹𝗶𝗸𝗲 𝗶𝗻 𝗽𝗿𝗮𝗰𝘁𝗶𝗰𝗲: Delivered an ERC20 token that reached an $18M market cap. Helped a blockchain startup close $10M in funding with audit-ready smart contracts. Built a multi-chain NFT marketplace that generated $1M+ in sales. More recently, built AI agents and LLM integrations that automate trading logic, customer workflows, and on-chain data analysis. These aren't team numbers. These are projects I was directly responsible for. 𝗪𝗵𝗮𝘁 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 𝘀𝗮𝘆 𝗮𝗳𝘁𝗲𝗿 𝘄𝗼𝗿𝗸𝗶𝗻𝗴 𝘄𝗶𝘁𝗵 𝗺𝗲: "Delivered ahead of schedule and the contract logic was airtight, exactly what we needed before our raise." "Came back for a second project. That says everything." "Flagged a vulnerability our previous dev missed. Saved us from a serious exploit." 𝗪𝗵𝗼 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵: I work with founders, CTOs, and product teams building serious blockchain infrastructure or AI-powered products, not weekend side projects. If your project involves real capital, real users, or a real audit, that's where I'm most useful. 𝗔𝗜 & 𝗟𝗟𝗠 𝘀𝘆𝘀𝘁𝗲𝗺𝘀: AI agents, LangChain workflows, OpenAI/Claude API integrations, automated trading and analytics agents, chatbot and support automation 𝗗𝗲𝗙𝗶 𝗽𝗿𝗼𝘁𝗼𝗰𝗼𝗹𝘀: DEX platforms, staking systems, yield farming, token launchpads, cross-chain bridges. 𝗧𝗼𝗸𝗲𝗻 𝗲𝗰𝗼𝘀𝘆𝘀𝘁𝗲𝗺𝘀: ERC20, BEP20, SPL tokens with custom tokenomics, vesting, and IDO/ICO structures 𝗡𝗙𝗧 𝗽𝗹𝗮𝘁𝗳𝗼𝗿𝗺𝘀: marketplaces, GameFi, dynamic NFTs, royalty systems, IPFS hosting 𝗦𝗺𝗮𝗿𝘁 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁 𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆: audit support, vulnerability assessment, gas optimization, test coverage with Hardhat and Foundry 𝗖𝗿𝘆𝗽𝘁𝗼 𝗮𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻: MEV bots, arbitrage systems, Telegram trading bots, copy trading infrastructure, now paired with AI decision layers 𝗙𝘂𝗹𝗹 𝘀𝘁𝗮𝗰𝗸 𝗱𝗔𝗽𝗽/𝗔𝗜 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁: from Solidity or Rust contracts to Python AI backends to React/Next.js frontend 𝗧𝗲𝗰𝗵 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵 𝗱𝗮𝗶𝗹𝘆: 𝗦𝗺𝗮𝗿𝘁 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝘀: Solidity, Rust, Hardhat, Foundry, Truffle, Brownie, Anchor, OpenZeppelin 𝗔𝗜/𝗟𝗟𝗠: LangChain, OpenAI API, Claude API, vector databases, AI agent frameworks 𝗖𝗵𝗮𝗶𝗻𝘀: Ethereum, Solana, Binance Smart Chain, Polygon, Avalanche, TRON 𝗙𝗿𝗼𝗻𝘁𝗲𝗻𝗱: React.js, Next.js, TypeScript 𝗕𝗮𝗰𝗸𝗲𝗻𝗱: Node.js, Python, PostgreSQL, MongoDB, MySQL 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀: Web3.js, Ethers.js, MetaMask, WalletConnect, Infura, Alchemy, Chainlink, IPFS 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗲𝘀 𝗜'𝘃𝗲 𝗯𝘂𝗶𝗹𝘁 𝗳𝗼𝗿: DeFi and crypto infrastructure, protocols, exchanges, launchpads, NFT and GameFi, marketplaces, staking dApps, metaverse integrations, blockchain fundraising, ICO/IDO platforms, investor-facing audit-ready contracts, AI-powered automation, trading agents, on-chain analytics, support and workflow bots, Enterprise blockchain, supply chain, real estate tokenization, identity systems 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸: I don't disappear after handing over code. Most of my clients come back for the next project and the one after that. I give daily or weekly updates depending on the project's scope, flag problems before they become blockers, and write contracts and systems that your auditor won't send back with a list of critical findings. 𝗖𝗼𝗺𝗺𝘂𝗻𝗶𝗰𝗮𝘁𝗶𝗼𝗻: Slack, Telegram, JIRA, Trello, GitHub, whatever your team already uses. 8 years. 3 major outcomes. 0 exploited contracts.
