🧑‍💻 About Me

I'm an independent Web3 developer specializing in agentic finance, stablecoin infrastructure, and on chain cryptography. I build end to end systems from smart contracts to backend execution layers to user interfaces entirely solo.

  • 🤖 Building autonomous AI agent wallets and agentic execution systems for the onchain economy
  • 💵 Developing stablecoin protocols and DeFi integrations across Ethereum, Base, Arc, Optimism, Arbitrum
  • 🌉 Deep experience with Circle's product stack USDC, EURC, CCTP, Bridge Kit, Gateway, x402
  • 🔐 Researching Fully Homomorphic Encryption (FHE) with Zama and Zero Knowledge Proof systems
  • ⚡ Active builder on Arc Testnet, Tempo Testnet and Base shipping production grade contracts and live applications
  • 📊 Building onchain data marketplaces and oracle surfaces for agent driven micro payment flows
