AI Developer & AI Agents | Web3, Blockchain, API Integration, Node

🚀 AI & FULL-STACK ENGINEER | AI AGENTS · WEB3 · API INTEGRATION · NODE I build production-ready AI systems, Web3/blockchain applications, and full-stack SaaS platforms. 10+ years and $90K+ delivered on Upwork across AI agents, smart contracts, complex API integrations, and scalable backends — so what I build actually ships and runs in production. My focus is beyond basic ChatGPT wrappers or demo code. I build systems that reason, use tools, call APIs, handle real business logic, and run reliably at scale. ━━━━━━━━━━━━━━━━━━━━━━ 🤖 AI AGENTS & AUTOMATION ✓ Custom AI Agents & Multi-Agent Systems ✓ Tool Calling & Function Calling ✓ RAG Applications & Knowledge Systems ✓ AI Chatbots, Assistants & Voice AI ✓ AI Workflow Automation (n8n, Make, Zapier) ✓ LLM & API Integrations Technologies: Claude, OpenAI, LangGraph, LangChain, Pinecone, pgvector ━━━━━━━━━━━━━━━━━━━━━━ ⛓️ WEB3 & BLOCKCHAIN ✓ Smart Contract Development ✓ dApp Development ✓ NFT Marketplaces ✓ Web3 / Wallet Integrations (MetaMask, WalletConnect) ✓ Token Development & Blockchain Integrations ✓ DeFi & On-Chain Logic ━━━━━━━━━━━━━━━━━━━━━━ 💻 FULL-STACK DEVELOPMENT ✓ Scalable SaaS Platforms & MVPs ✓ Node.js, Express, NestJS backends ✓ React, Next.js frontends ✓ REST APIs, GraphQL, Webhooks ✓ Microservices & clean architecture ━━━━━━━━━━━━━━━━━━━━━━ 🔌 API & SYSTEM INTEGRATION ✓ Complex Third-Party API Integration ✓ REST APIs & Webhooks ✓ Payment & CRM Integrations ✓ Custom Connectors & Data Synchronization ━━━━━━━━━━━━━━━━━━━━━━ 🛠️ TECH STACK JavaScript | TypeScript | Python Node.js | Express | NestJS React | Next.js Solidity | Web3.js | Ethers.js MongoDB | PostgreSQL | Redis REST APIs | GraphQL | Webhooks Docker | CI/CD | AWS | GCP ━━━━━━━━━━━━━━━━━━━━━━ 🤝 WHY CLIENTS HIRE ME ✓ 10+ years, $90K+ earned, 100% Job Success ✓ Rare mix: AI + Web3 + real full-stack engineering ✓ Clean, scalable, production-grade architecture ✓ Clear communication and reliable delivery If you need someone who can build AI systems, Web3 applications, or full-stack platforms — and make them work reliably in production — I can deliver it properly. ━━━━━━━━━━━━━━━━━━━━━━ 🔎 SKILLS & KEYWORDS AI Developer, AI Agents, Agentic AI, LLM, RAG, Claude, OpenAI, LangGraph, Web3 Developer, Blockchain Developer, Smart Contracts, Solidity, dApp, NFT, Full-Stack Developer, Node.js, React, Next.js, NestJS, API Integration, REST API, SaaS Development, Automation
