I am Chibueze Louis, a highly skilled Solidity Contract Engineer specializing in the blockchain ecosystem with over 5 years experience writing and auditing smart contracts. As a smart contract researcher and auditor, I dive deep into the intricacies of your code, meticulously analyzing and ensuring its security and functionality. My expertise goes beyond development – I can help you identify potential vulnerabilities, refine your code, and provide comprehensive audits to ensure your smart contracts are rock-solid. With an unwavering commitment to quality, I pride myself on delivering secure and efficient solutions that meet industry standards. I also prioritize effective communication, breaking down complex topics into easily understandable explanations. Whether you need assistance with smart contract development, code audits, or expert guidance in the blockchain space, I'm here to help. Feel free to reach out so we can discuss your project requirements and explore how we can collaborate to bring your vision to life.

Developed and successful in the market of enterprise-level solutions, from E-commerce products to Decentralized applications — with a track record to prove it. Most developers build features. I build complete products. I am a SaaS founder and full-stack engineer who has taken multiple applications from idea to live users — oneshare (my own SaaS), — plus Web3 systems on Ethereum and Solana when the business actually needs blockchain. But here's what I have learned founding and shipping real products: Most clients don't need a developer. They need someone who understands their business problem first, then builds the right solution. Thats exactly how I work. What I build: → Full-Stack Web Applications — end-to-end, production-ready, built to scale → Web3 & Blockchain — DApps, smart contracts, token systems on Ethereum & Solana → SaaS Platforms — from your idea to a live product real users actually pay for → Ecommerce Solutions — custom storefronts, integrations, conversion-focused builds What makes me different: I have coded and launched also my own SaaS products — so when I build yours, I am not guessing what good looks like. I know what it costs when a product is built wrong the first time — wrong architecture, bloated scope, no thought for growth. So before I write code, I ask the right questions, challenge assumptions, and make sure we are solving the real problem. You get a complete application. Not a pile of disconnected features. Tell me what you are building or where you are stuck. I'll give you an honest answer — before we even talk about hiring me.

25 projects delivered. 100% Job Success. Code that ships clean and stays secure. I build full stack web applications and blockchain systems from React/Next.js frontends to Solidity smart contracts. Whether you need a production web app, a DeFi platform, or a token launch, I handle architecture, development, and deployment end-to-end. My stack: Solidity, Hardhat, Ethers.js, React, Next.js, Node.js, Laravel, Flutter across Ethereum, BSC, Solana, and Polkadot. I focus on clean architecture, security, and code that works in production not just in dev. Have a project? Message me and I’ll review your requirements for free before we start.

Have you ever launched a blockchain project that looked great on paper but fell apart in production? I've spent 8 years making sure that doesn't happen for token launches, DeFi protocols, NFT platforms, and everything in between. 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. 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 - not weekend side projects. If your project involves real capital, real users, or a real audit, that's where I'm most useful. 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 𝗙𝘂𝗹𝗹-𝘀𝘁𝗮𝗰𝗸 𝗱𝗔𝗽𝗽 𝗱𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁: from Solidity or Rust contracts to React/Next.js frontend and Node.js/Python backend 𝗧𝗲𝗰𝗵 𝗜 𝘄𝗼𝗿𝗸 𝘄𝗶𝘁𝗵 𝗱𝗮𝗶𝗹𝘆: 𝗦𝗺𝗮𝗿𝘁 𝗰𝗼𝗻𝘁𝗿𝗮𝗰𝘁𝘀: Solidity, Rust, Hardhat, Foundry, Truffle, Brownie, Anchor, OpenZeppelin 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 & crypto infrastructure - protocols, exchanges, launchpads NFT & GameFi - marketplaces, staking dApps, metaverse integrations Blockchain fundraising - ICO/IDO platforms, investor-facing audit-ready contracts Crypto trading & automation - bots, arbitrage systems, on-chain analytics 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 project scope, flag problems before they become blockers, and write contracts 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.

I build production AI software: AI agents, autonomous workflows, RAG systems, voice agents, MCP integrations, and agents that safely handle payments and credentials. The hardest problem in AI right now is not building an agent. It is trusting one. Agents that touch real money, customer data, or production systems get drained, jailbroken, or go rogue — usually within weeks of launch. That is the problem I specialize in, and my proof is public: - I wrote DCP, an open-source security layer for AI agents: a local encrypted vault where the agent requests actions but never holds your keys. On GitHub, Apache 2.0. - I run 1ly.store, a live marketplace where AI agents discover and pay for services in USDC — settling real payments daily on Base and Solana. - One agent I shipped onboarded 20K users in its first 7 days. - 8+ years shipping production AI and blockchain systems, 100% Job Success, for clients who have raised $42M+ combined. Recent work includes: - Production AI agents, single and multi-agent, that take real action across business tools - Custom MCP servers and integrations — connecting AI to Notion, Slack, CRMs, databases, and your own software - RAG and document intelligence systems with hybrid retrieval, citations, and measured accuracy - Voice AI agents that answer, qualify, and book calls for real businesses - Agentic payments: x402 integrations and agents that transact on-chain safely - Agent security: key isolation, human approval loops, spend limits, red-teaming, and production audits I am a good fit if you want an agent built right the first time — whether you are starting from an idea, a messy manual process, or an existing system that breaks with real users, real data, or real money. If you need a chatbot demo, I am not your guy. Send me 2–3 sentences on what you are building or what you want automated. I will reply within 24 hours with a practical plan or an honest pass.
