Agent-ready portfolio of Ruben Marcus, AI Fullstack Engineer. A cinematic WebGL site for humans and a protocol surface for agents: a remote MCP server (io.github.rubenmarcus/portfolio, on the official MCP Registry), a public Agent Skill, llms.txt and a plain-text resume over curl. Built with Astro 5, Svelte 5, Three.js and GSAP.
Personal portfolio. **Agent-ready · humans welcome.** Terminal-green and agent-first: a cinematic 3D hero, a blog written for humans and machines, and an MCP server so AI agents can read the resume and book a call without ever rendering the page. **Live:** [rubenmarcus.dev](https://rubenmarcus.dev) - [Astro 5](https://astro.build) (islands, content collections, i18n EN/PT)
