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

agent-ui-kit: accessible React components for agent runs: tool timelines, human-in-the-loop approvals, per-hunk diff review and run telemetry. React 19, AI SDK v7, shadcn registry, WCAG AA.

ask-my-site: a drop-in ask box for any website with a build-time index, in-memory hybrid search and streaming answers with citations. No vector database.

design-system-mcp: gives coding agents ground truth about your React design system, plus a linter they run on their own UI.

Live demos: agent-ui-kit playground · ask-my-site docs assistant

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.
