Are you still demoing your multi-agent project on localhost? Staring at working code wondering how to ship it? Learn how to turn your Agent Development Kit project into a scalable, production-ready product in minutes. I'll use Gemini CLI to build a multi-agent system with ADK and Gemini 3—wiring up File Search API and Nano Banana Pro, all coordinating through MCP and A2A. Watch it go from laptop to Agent Engine, adding Firestore for memory and Antigravity for the UI. No slides. Just live deployment. This is when announcements become architecture.
