I built the system UN IFAD uses to track $300M+ in agricultural supply chain value. It won the 2024 World Future Award. Before that, blockchain infrastructure for the DHS Silicon Valley Innovation Program, and CasperSwap DEX, audited by Quantstamp and Halborn. ⚙️ 𝗔𝗜 𝗦𝗬𝗦𝗧𝗘𝗠𝗦 Most AI and blockchain projects fail at the seam between the two. One developer handles AI, another handles blockchain, and nobody owns where they connect. I own the full architecture. On the AI side, I build RAG pipelines, multi-agent systems using LangGraph and CrewAI, LLM orchestration layers, voice AI, and agentic workflow automation using n8n. I have shipped production systems with LangChain, pgvector, Pinecone, Weaviate, OpenAI, and Anthropic SDK. One of them is an AI-powered legal intake system running on WhatsApp via Meta Cloud API and Twilio Voice, built with Claude and Llama 3.3 70B, handling real client conversations at scale. I also build custom AI chatbots, conversational AI systems, AI calling agents, and AI-powered SaaS platforms for healthcare, legal, and enterprise clients, including EHR/EMR integration and appointment booking automation. 🔗 𝗕𝗟𝗢𝗖𝗞𝗖𝗛𝗔𝗜𝗡 𝗦𝗬𝗦𝗧𝗘𝗠𝗦 On the blockchain side, I write smart contracts in Solidity and Rust, deploy across Ethereum, Solana, XRP Ledger, and Casper, and build on Layer 2 networks and Hyperledger Fabric. I have delivered DeFi protocols, DAO governance frameworks, RWA tokenization platforms, NFT development, crypto wallet development, prediction market platforms, and MEV systems. I work with Foundry, Hardhat, Ethers.js, Wagmi, Slither, and The Graph. My smart contract work has been audited by Quantstamp and Halborn. 🛡️ 𝗖𝗢𝗠𝗣𝗟𝗜𝗔𝗡𝗖𝗘 & 𝗗𝗘𝗣𝗟𝗢𝗬𝗠𝗘𝗡𝗧 I also build AI agents and agentic workflow systems that replace manual business processes, API integrations, prompt engineering pipelines, semantic search, and vector database infrastructure. For teams that need on-premise LLM deployment, I use Ollama. For cloud, I deploy on AWS, GCP, and Azure with Docker and CI/CD pipelines. Frontend work is React, Next.js, and TypeScript with FastAPI and NestJS on the backend. Where I work best is at the intersection of AI automation and blockchain verification, inside compliance frameworks including HIPAA, SOC 2, GDPR, and ZATCA. If AI makes the decision, blockchain proves it happened. That is the kind of system regulated industries actually need. Before any engagement I do one scoping call. I will tell you exactly what to build, what not to build, and why. If blockchain or AI does not belong in your project, I will say so. Message me with two lines about your project. I will tell you within 24 hours whether I can help, and how. 🔑 𝗦𝗞𝗜𝗟𝗟𝗦 & 𝗧𝗘𝗖𝗛𝗡𝗢𝗟𝗢𝗚𝗜𝗘𝗦 Claude Code, Gemini, Python, Node.js, MCP, Supabase, GitHub Copilot, Cursor, Lovable, Agentic AI, AI Coding Workflow, LLM Integration, Business Process Automation, Telegram Bot Development, Vibe Coding, SaaS Development, Chatbot Development, Production Hardening, Deployment Pipeline, Prototype, AI Operating System, Machine Learning, Layer 2 Development, TON Blockchain, Smart Contract Audit, Blockchain Architect, Web3 Development, MEV Bot, Tokenomics, Testing, AI Full-Stack, AI Systems Architect, Automation Architect, Data Science, Product Engineer, TensorFlow, PyTorch, Scikit-Learn, Cloud Deployment, AI-Generated Code, CV, Real-Time Conversational Systems, Product Development, MVP, AI App Development, Top 1% AI Engineer, Automatic Speech Recognition, Smart Contract Engineer, ERC20, Asset Management System, Solidity Smart Contract Security, Prediction Based Market Platform, Crypto Sniping Bot, Uniswap V2/V3, PancakeSwap, Crypto DeFi Expert, Wallet Intelligence Monitoring, Advanced LMS, Tachograph Compliance Engine, Algorithm Development, Regulatory Compliance, Fractional AI Architect, Applied AI Engineer, Full-Stack SaaS Developer, AI Personal Operating System Developer, AI Solutions Architect, Healthcare SaaS Platform, Agentic AI Architect, Agent Enterprise Ecosystem, Pathwaize Intelligence, Complex System Rebuilt, AI Voice Automation, AI Infrastructure Engineer, LLMOps Engineer, Lead Cryptography & Systems Architect, Multi-Model Workflow, Behavior Analysis & Monitoring Expert, Secure HIPAA Compliant, OpenAI RAG Platform, AI Revenue Systems Builder, Healthcare AI Security Expert, Machine Learning Engineer, AI-Native Software Engineer, AI Pricing Bot Developer, Custom SaaS Platform Development, Vibe Coding Developer, AI Fuel Intelligence, Senior Product Owner/Manager, Startup GenAI SaaS, Healthcare AI Integration Engineer, AI Model Integration, Healthcare Appointment Booking Automation, Healthcare Systems, Solidity contract architecture
