Diogo Esteves. Staff Full-Stack AI Engineer. I build AI-native products end to end, from backend to UI.

diogo-studio.com  LinkedIn  Email

Full-stack engineer, 10+ years in, focused on AI. I build AI products end to end: agents and retrieval, the APIs and data behind them, and the interfaces people use. I've run engineering as VP at an AI-first startup, built a design system adopted across Fortune 1000 governance software, and shipped streaming UI to millions of Peacock subscribers. I'm equally at home as a Staff IC inside a large org or leading engineering at an AI startup. Lisbon-based, remote on US-aligned hours.

Now

  • Fueled: Lead Engineer, Web Applications. Leading architecture for enterprise web applications.
  • Open source: AI developer tooling, built in public. Three projects below.

Open source

all-three.mp4

onsystem: keeps coding agents on your design system. It knows your real components, props and tokens and catches what an agent invents; 4% false positives on 10 public repos. Claude Code plugin, MCP, CI check, shadcn/ui.

ondocs: makes your docs answerable by people and agents from one static index: a cited Ask box, an MCP server and llms.txt. No vector database, no vendor. Docusaurus, Starlight, MCP, llms.txt.

signoff-ui: review what your agent changed and approve what it may do. React components for multi-file diff review and tool approvals with rules. AI SDK 6 & 7, AG-UI, shadcn registry, WCAG AA.

Websites, each with docs and a live demo: onsystem (a check_ui playground for your own code) · ondocs (ask the docs, or connect an agent over MCP) · signoff-ui (review and approve a scripted agent run)

Featured

diogo-studio: my portfolio as an explorable 3D studio, with an AI agent that answers questions about my work. Built with Next.js 16, React 19, React Three Fiber and the AI SDK.
