};I build agent systems that survive contact with production — tool-using LLMs wired through MCP, grounded by RAG, gated by eval harnesses, and instrumented end-to-end so failures are observable instead of mysterious. Before AI I spent four years deep in Web3, leading an MPC wallet-infrastructure team across cryptography, smart contracts, and Rust.

Design intent before code: I write the evals and guardrails before a line ships, then let observability close the loop — every production failure feeds the next iteration instead of disappearing.

🛡️ Bulkhead — Durable Agent Execution Runtime · 2026 · demo
An open-source execution harness for LLM agents designed for crash resilience and side-effect guarantees. Features hard crash recovery (kill -9), queue lease management via PostgreSQL SKIP LOCKED, checkpoint replays, and outbox idempotency key deduplication to prevent double-spending purchase orders.

🔐 INTU — Web3 onboarding via MPCCTO · Lead Engineer Open-source NPM package orchestrating distributed key generation (DKG) and multi-party computation, removing seed phrases from the onboarding flow. Cross-chain transaction flows across EVM networks, bridged to Solana — sending a Solana tx authorized by an EVM signature. Self-hosted The Graph indexers for chains without hosted support.

☁️ Drafture — Plain-English → safe, costed AWS architectureLive · 2026 · You describe a system in plain English; Drafture returns a recommended AWS design as a labeled data-flow diagram, ordered setup steps, and cost estimates in each service's native unit — across budget / balanced / resilient tiers, with a security floor baked into all three. The LLM returns a validated typed graph; the backend renders Mermaid diagrams and cost tables deterministically from it.

Quant Research · WIP Backtest harness and execution research for systematic futures strategies — applying the same eval + observability discipline I use on AI agents to strategy selection, slippage modeling, and live risk.

Selected Project · 2026 LLM agent layered onto an open-source EHR that reads patient charts and relays clinical context on demand. Lab-report ingestion pipeline produces summaries with source-page citations, so clinicians can verify any agent-surfaced claim — a RAG pattern tuned for high-stakes clinical use.

Autonomous coding agent An agent that triages open GitHub issues, reproduces the bug, drafts a fix, and opens a PR — closing the loop from issue to reviewable change. Proof: medplum/medplum#9293 — an upstream OSS fix landed fully agentically (working branch).

🍻 Happy Hour Friends — Crowdsourced happy hour finderLive · 2026 · Fully agent-operated site: every update — parsed automatically from the web or submitted by users — passes strict agentic moderation gates (classify → verify, versioned prompts, audited apply path) before going live. The test: can my agent safeguards run the site without my intervention? The product itself is dead-simple — venues and deals in one sortable, filterable view, kept current by crowdsourcing.

I burn a lot of tokens — on purpose. But spending them to look busy is waste.
The craft is signal per token: tight context, sharp evals, and failure modes that are observable instead of mysterious.
Every system above was designed, built, and shipped on a ~$100/month plan.
