Senior full-stack engineer building agent systems, developer tooling, and AI infrastructure.
Backend / full-stack software engineer at Knox Financial (Boston), 2020–2021; since then independent, shipping public agent and on-chain products. I like products with real operator surfaces, tight feedback loops, and enough technical depth that the implementation actually matters.
consensus-cli— local-first observability for Codex, OpenCode, and Claude Code sessions. Published to npm (Apache-2.0, v0.1.5), 8,000+ lines of TypeScript, runs locally with no hosted service.- SigilX — agentic verification protocol deployed on Base: Solidity contracts, Privy smart-wallet flows, x402 stablecoin (USDC) payments, and a React/Next.js streaming frontend over a multi-service backend.
x402janus— payment/security infrastructure for agent and API surfaces: x402 challenge/response, wallet-aware access control, signed receipts, and auditability. (Live x402 endpoint — returns HTTP 402 by design.)SpendOS— autonomous spending governance with human approval flows and on-chain audit trails.
I work across product UI, backend services, agent runtimes, smart contracts, test systems, and deployment/ops. The through-line is shipping systems that are useful, measurable, and robust under real use — not demo-only AI.
Senior full-stack product engineering, AI/agent systems, developer tooling, platform engineering, or forward-deployed engineering. Boston or remote.
