Hi, I'm Patrick Galyen — a full-stack + smart-contract developer

I design, build, and ship production software solo, end to end — frontend, backend, Solidity, and the infra under it. Based in Northern Virginia · open to contract and full-time work.

Things I've built and shipped

🏗️ TradeGuard — trade-guard.pro A construction-compliance SaaS, built and run solo. Next.js + Prisma, Stripe billing, QuickBooks Online OAuth vendor import, automatic PDF/Certificate-of-Insurance extraction, a subcontractor self-upload portal, 50-state compliance library, and email/SMS expiry alerts. SQLite on Railway with Litestream replication. A real, live product — not a demo.

⚡ gate402 — pay-per-call API gateway for AI agents (x402 / HTTP 402 over USDC) Rent metered compute and open-model LLM inference per request, plus crypto/finance data endpoints. Published packages: gate402-next (Next.js middleware), gate402-mcp (MCP server, 17 tools), and gate402 on PyPI.

🔒 Smart-contract security research Verified Foundry PoCs against Aave-, Morpho-, and Alchemix-class lending protocols, plus a working flash-loan liquidation / oracle-dislocation engine across Base, Arbitrum, and Optimism (flash loans, DEX routing, MEV mechanics). Comfortable reading unfamiliar Solidity and proving an exploit end to end.
