I'm a Senior Developer Advocate at GitHub. I connect developer tools with business strategy, helping teams build skills, improve workflows, and grow their capacity to deliver.

I build, teach, and bring developers together in English and Spanish. AI is part of that work, alongside our creativity, experience, and judgment.

I'm also an Agentic AI Foundation Ambassador.

Fundamentals first, always.

• Agent Circuit: A browser racing game featuring six coding agents and Blender-built characters.
• Claw Relay: Connect AI agents to a real browser with scoped permissions, site restrictions, and audit logging.
• Team X-Ray: A VS Code extension that uses git history to help you find who knows which parts of your codebase.
• Proof Agent: Give AI-generated changes to a separate agent for review, with evidence-backed verdicts.
• publish-to-pages: An agent skill that turns presentations and web content into live GitHub Pages sites. Also available in github/awesome-copilot.
