Most AI apps look great in a demo and fall apart when real users show up. I build the ones that hold up. I've spent 7 years building frontends (React, Next.js, TypeScript, Tailwind, shadcn/ui), 4+ years on production backends (Postgres, Prisma, Supabase), and the last year shipping multi-model LLM features into real products. I also co-founded a product and ran its engineering up to a live product trusted with around $1M of user funds, so I know what real production takes, not just what a demo looks like. These days I use AI tools like Claude Code every day, which is how I ship in weeks what usually takes months without the code turning into a mess. Wherever you're starting from, a rough idea, a stalled prototype, or a working product that's beginning to break, I take it and turn it into something solid you can put in front of real users and grow. I handle the whole thing end to end: the product, the AI inside it, and everything around it that has to work for it to count. Stack: Next.js, React, TypeScript, Tailwind, Node.js, Supabase, Postgres, Claude, OpenAI, Vercel AI SDK, Stripe, Vercel. Send me what you're building and where it's at today, and within a day I'll tell you if I can help and what it'll take.

I'm a Blockchain & AI Developer specializing in building secure smart contracts and decentralized applications (DApps), as well as intelligent machine learning systems. I help clients automate operations, streamline workflows, and ensure transparency using blockchain and AI technologies. My code is rigorously tested and audit-ready to guarantee security and reliability for your projects. With a full-stack skill set, I can take your idea from concept to launch - handling everything from smart contract development to frontend integration. Services I Offer: ✅ Smart Contract & DApp Development: Development of secure smart contracts (Solidity, Rust, Move, etc.) and blockchain DApps with thorough testing and best practices for security. I write clean, efficient code and can also audit or improve existing contracts. ✅ Token Launch & ICO/IDO Support: End-to-end token development - minting cryptocurrencies or tokens (ERC-20, BEP-20, Solana SPL, etc.), setting up presale or fair-launch mechanisms, and advising on tokenomics. I ensure your token launch is smooth and compliant with industry standards. ✅ AI & Machine Learning Solutions: Building and training ML models (Python, TensorFlow, PyTorch) for prediction, classification, or data analysis. I can integrate these models into your software or blockchain system to add intelligent features like predictive analytics or decision automation. ✅ Blockchain-AI Integration: Creating systems where AI algorithms interact with blockchain data. For example, blockchain-based AI marketplaces, smart contracts that trigger AI computations, or analytics on ledger data. This integration ensures data integrity, automation, and transparency in AI-driven decisions. ✅ Full-Stack Web3 Development: Complete solution development from frontend to backend. I build responsive frontends (React, Vue, Web3.js) and robust backends (Node.js, Python, REST APIs) that seamlessly integrate with blockchain networks. This means I can develop your project's entire tech stack, delivering a one-stop solution. With over 2 years of development experience, I bring both technical expertise and a passion for innovation to every project. I pride myself on clear communication, meeting deadlines, and delivering value to my clients. Let’s work together to build the decentralized, AI-powered solution you envision! 🚀
