I build AI agents with real money on the line.

An operating system + customer-facing AI sales agent for a Miami medical practice doing ~$100K/month. Replaced a 13-tab spreadsheet and hours of daily manual texting. The agent (Anthropic tool-calling) handles reorders, pricing, order status, and referrals over SMS; a human-takeover inbox with per-thread CRM context catches everything else.

Inside the OS: an assistant with read and write tools across the whole system. Every write is proposed, and executes only after explicit operator confirmation. Evals run on a curated golden-conversation set, not volume. Payment→fulfillment proven end-to-end on prod: real card charge → order paid → fulfillment SMS delivered.

A complete store for a ~$1M/year one-of-one luxury resale brand (42K+ Instagram): custom theme ported from an approved prototype, metafield data model, 31 automated collections with a sold-vanish rule, payments onboarding, and a pre-checkout policy gate that records acceptance on the order itself. Chargeback armor that replaced a paid app.

Feeding it: an idempotent Python import pipeline (22 unit tests, run manifests) that turns a messy human spreadsheet + Drive folders into a clean catalog. Immutable archive-number identity, staged media normalization, and publish gates that refuse any product missing photos, condition, or location. Full-sheet imports run at 0 errors.

Three complete, visually distinct storefront directions: 21 pages, a 10-step bespoke-request wizard, real catalog data, PDPs aware of three fulfillment classes. Designed, built, and deployed in one day with a two-model pipeline: Claude plans and verifies, Codex implements, with adversarial plan review to an explicit APPROVED verdict before any code.

Because a manual spot-check once let a visual defect through, the pipeline includes an automated bounding-box overlap scanner across all 21 pages × 3 viewports. AI-generated storefronts only count when a machine, not a vibe, says they're right.
