Hey there 👋🏻

I'm Shawn, a software engineer who breaks and builds things onchain and off.

Currently my days are devoted to:

• 🤖 building agentic AI systems and LLM-powered pipelines.
• ⛓️ hacking on DeFi protocols and onchain infra.
• 🛡️ shipping developer tools and indie building products.
• 🏆 winning hackathons (9x national, still going).
• 👌🏻 contributing to open-source projects.
• ⚽️ enjoying life.

things i've built:

products & onchain

• polynuts — non-custodial crypto prediction market on Base · pump/dump/range bets settled trustlessly on Thetanuts options vaults
• Vestra — AI research desk for pre-IPO tokens on Solana · Bull, Bear & Neutral analysts debate the same evidence, a Council checks it and writes a cited brief
• ParkTheBus — peer-to-peer football prediction market on Solana · post an RFQ for any event ("Ronaldo to cry"), market makers quote the odds, settled on-chain with zero house edge
• bequeath — Uniswap v4 hook that makes an LP position inheritable and self-funds a monthly annuity from its own fees · submission for the Uniswap Hook Incubator program
• AgentProof — cryptographic work receipts for AI agents · proves who did the work and that nothing was tampered with
• HedgeLP — delta-neutral Uniswap v4 LP with atomic GMX hedging
