We have all seen the flashy GenAI demos but what happens when you actually need to run one in production?

In this session, I will share how I built a Java service on Vertex AI that takes real business data (Google Analytics + revenue goals) and turns it into useful customer personas for the marketing department.

I’ll walk you through the code and configs step by step:

1. how I structure prompts to keep the model grounded in context,

2. what Vertex AI settings really matter (project, region, model IDs),

3. the service layer code that ties everything together, and

4. how I packaged and deployed it on Cloud Run with secrets, scaling, and monitoring.
