How much of a genuine realtime system can you build in a lunchtime's worth of programming? In this live-coding session we'll build a real-time, Kafka-driven sales dashboard from scratch and see how you:

- Set up a Kafka Consumer with Python.
- Easily handle real-time Stream Processing with ksqlDB.
- Build out a WebSocket server to broadcast live data to your users.
- Create a basic React app to visualise data in a way anyone can access.

We'll start with an empty directory and by the end, you'll have all the foundational pieces of a dashboard that could serve KPIs to everyone in your organisation, or just form the basis of your next lunchtime hacking session.
