Über diesen Service

Need a senior Web3 + AI developer to build an AI x Blockchain dApp that actually ships? I build production-grade dApps with smart contracts + agentic AI, ideal for founders who want AI agents that can read data, call tools, and execute on-chain actions.


What I can deliver:

  • EVM / L2 dApps (Ethereum, Arbitrum, Base, Polygon), WalletConnect/MetaMask
  • Solidity contracts: tokens/NFTs, token gating, registries, payments, DeFi modules
  • Agent workflows: tool-calling, permissions/policies, observability, admin dashboard, run history + DB
  • x402 paywalled APIs / metered usage, ERC8004 identity/delegation patterns (if needed)
  • Clean repo, tests, deployment guide (testnet/mainnet-ready)


Optional: RAG + memory (pgvector/Pinecone), usage metering, basic security review & gas abstraction.


Stack: Solidity (Foundry/Hardhat), Next.js/React, Node.js/Python, Postgres, APIs.


Message me your idea + chain + timeline and Ill suggest a clear MVP scope, milestones, and architecture.
