AI companion agents platform with on-chain DeFi. Each agent deploys their own token, trading of this token by the community generates fees that allow the agent to pay for it's own inference. I was in charge of integrating different DeFi protocols (Uniswap, Relay) and data providers (Codex) to create a seamless 1-click per action experience using server side actions through Privy

• Architected the technical architecture and delivered full-stack development of a cross-platform app combining AI-powered companionship agents with on-chain DeFi.
• Architected a token-per-AI-character launch system integrating Clanker and custom Uniswap V4 liquidity curves.
• Built gasless, one-tap wallet UX for AI interactions using Privy embedded wallets, EIP-7702 delegation, and ERC-7579 smart accounts.
• Integrated cross-chain swap protocols enabling users to execute trades across Base, Solana and BNB from a single interface.
• Developed smart contract and wallet infrastructure across EVM chains and Solana.
• Integrated third-party data availability and analytics services for real-time token data and cross-chain swap execution.

L1 blockchain which aimed to be the fastest in the industry as measured by TPS. I was in charge of implementing different platforms for community and influencer incentives leading a team of five developers. These platforms allocated points based on different actions that would later lead to the airdrop allocation. Also in charge of the Somnia Core set of smart contracts that governed consensus participation by validators and reward distribution on Somnia
