One Codebase, 15 Apps: Building White-Label Apps with React Native 

What does it take to ship 15 apps from a single React Native codebase? In this talk we'll explore the white-label approach end to end — from iOS targets and Android flavours through a custom Metro resolver and filename conventions on the JS side, to a shared Design System and a robust CI/CD pipeline. We'll also cover analytics, crashlytics, and a practical scaling checklist so you know what to watch out for before your next brand goes live.

JavaScript Meets RAG: Building AI Agents with Google ADK 

This talk showcases how modern Retrieval-Augmented Generation (RAG) agents can be created using JavaScript with Google's Agent Development Kit (ADK). Instead of focusing on theory, we'll explore what becomes possible when LLMs are connected to private documents through clean, declarative tools and structured API calls. By looking at document ingestion, and semantic retrieval in practice, you'll see how JavaScript and ADK enable production-ready, document-aware AI systems without heavy frameworks or custom vector infrastructure.
