AI SUPPORT TRIAGE 01 / 05

Services01

What I take on. Open to the right full-time role, too.

Service 01 Design Engineering & Design Systems Component libraries, design tokens, theming, Storybook, and accessibility, built in production React, TypeScript, and Next.js. Your app ships looking the way the design promised. I even build the Figma-to-code bridge itself (see Sorb).

Service 02 AI-Native & Agentic Delivery Agentic migrations, LLM orchestration, and MCP integration. Production AI features with measured outcomes, not demos.

Service 03 Internal Tools & Publishing Platforms Custom tools for managing digital content, from social publishing platforms to on-site promotion, plus the operator workflows around them.

About05

Nathan Hunsaker O'Brien — N. O'BRIENFOUNDER //

Nathan O'Brien is the founder of Metatoy, an independent, AI-native product studio. He has worked each new seam between design and engineering as it opened: the early commercial web, rich interactive applications, social platforms, and now agentic AI. He spent eleven years at BuzzFeed as a Staff engineer, owning the social-publishing frontend and proving the company's first agentic-AI patterns in production: a support-triage agent at 84% handling accuracy, a framework migration delivered in 8% of the estimate. Now he builds Sorb, a Figma→React design-token bridge, and woords, an infinite crossword for iOS, with two provisional patents filed. Before that came agency technical leadership for Target, BMW, Nike, and many more. Bring us what you imagine. We'll turn it into production software.
