I build the software a business runs on, from the first conversation to production.

The league's managers sign in with a personal link, declare keepers, trade players and picks, and ran the 2026 draft on a live board. The league rules live in a tested TypeScript domain layer. The invariants live in Postgres.

Customers build a cart, pick a vehicle size, choose a real open slot and book. The owner runs the business from a nine-tab console: dashboard, bookings, catalog with version history, calendar, financials, customers, marketing, content and notifications.

A business describes itself once. MarketingOS generates captions, images, carousels and video, runs every piece through a moderation classifier, then publishes it. An autonomy engine decides per platform and content type whether a post goes out, waits for review, or is blocked.

A small-business owner types one sentence and immediately gets a deterministic working console for their trade. Claude then streams a real multi-file React app. Nothing reaches the browser until every file compiles on the server, and the app runs in a sandboxed iframe.

A captain creates a golf weekend and shares a code. Every player joins from a phone. The app runs the trip: roster, team draft, match play, hole-by-hole scoring from every phone, skins and side games, a chat feed with photos, and a closing ceremony.
