I design interfaces for AI products and build them in code — clickable directions, not static mockups. Then I build the tooling that makes the next one faster. Design decisions stay with me; the execution between them I automate.

Selected work

AI agent platform for NetSuite

Now We Collide / TheBird.AI · marketing site · Next.js · 6 pages in 6 weeks

  • Designed the visual language that shows users when they are dealing with an AI agent, built from how agents already appear in the client’s product rather than invented for the website.
  • Set the rules for when and where an agent appears in the interface. Adopted into the client’s signed brand system and now going into the product itself.
  • Argued the homepage was overloaded and should be split across the site. When the client reached the same conclusion, I was handed the restructure.
Design-to-production agent pipeline — Claude Code plugin marketplace

Riu-F/riu-agents · 3 plugins · 15 agents · 9 skills · installed by the team

  • Built the pipeline the team produces client pages with: brand extraction, page build, then port into the client’s CMS. Around 40 pages shipped through it on a live client site.
  • The build runs unattended between two human checkpoints, so design judgment stays with a person and a new page starts from a short brief.
Client review kit with a closed AI feedback loop

Self-initiated internal product · Next.js + Supabase · used across client projects

  • Built a review layer that drops onto any prototype so clients comment directly on the page, instead of feedback arriving scattered across email and calls.
  • Each comment records what it was left on, so nobody has to describe which part of the page they mean.
  • Built for an AI to use, not just a person: Claude reads the open comments and makes the fixes on a branch.
Personal context system, and the AI brain built on it

Markdown vault + Next.js · Anthropic SDK · MCP

  • Built the system I work from: around 40 notes that record decisions and the reasoning behind them as the work happens, rather than documents written after it. My portfolio, my bios, and this résumé are generated from it.
  • Published a queryable version on my site — chat with it, or connect your own AI to it over MCP.
