Tan Z.

🧙‍♂️ Have a look at my portfolio: tanzhixuan. com I’m Jimmy 👋 I’ve been coding since I was 15, with 9 years of real-world development experience. I’m a 🏆 42× World Hackathon Champion, with projects backed by AWS, Coinbase, Ethereum, and Polkadot, and $250K+ in grants and ecosystem funding. My focus areas include complex SaaS platforms, AI-augmented and multi-agent systems with advanced RAG pipelines, and Web3 products spanning infra, payments, DeFi, advanced NFTs, RWA tokenization, SocialFi, RealFi, and Web3 tooling integrated into existing Web2 stacks. I thrive in fast-moving remote teams, where I rapidly decompose complex problems, design practical architectures, and ship production-grade prototypes that take ideas to production with minimal friction. ⭐ Core Competencies: ✓ Programming Languages: JavaScript, TypeScript, Python, Solidity, Cadence, Move, Java, C, and MATLAB ✓ Web3 & Blockchain Platforms: Circle CCTP, Account Abstraction (AA) stack, Polkadot JS, QuickNode (Functions & Streams), Alchemy, Wagmi, Viem, Ethers, RainbowKit, ENS, Sign Protocol, World ID and Mini Kit, Chainlink (Functions & VRF), Pinata, and Storacha ✓ Frameworks & Libraries: React, Next.js, Tailwind CSS, Wagmi, Viem, Ethers, RainbowKit, and WordPress ✓ AI & Multi-Agent Systems: OpenAI, ChatGPT, Claude, DeepSeek, LangChain, ChromaDB, CrewAI, Cursor, GitHub Copilot, Stability AI, ElevenLabs, Fish STT, and RunwayML ✓ Cloud, Backend & Infrastructure: Firebase Realtime Database, Firebase Firestore, AWS EC2, AWS S3, Vercel, Redis, Git, and VS Code ✓ Design & Visualization: Figma, Adobe Photoshop, Adobe Premiere Pro, and PowerPoint with professional visual storytelling and advanced transitions ✓ Enterprise & Specialized Systems: Pinata × LangChain JS tool classes for IPFS upload, query, deletion, and group management; IPFS WordPress Plugin; Storacha integrations; Blend 3D Face Reconstruction Engine; HyperAgile tokenized warehouse robotic automation system; and Discuss AI, an agent-led discussion platform
