Carmen San Diego GraphQL API Federation Challenge: Hunt for the Elusive Master Thief!

Embark on an exciting adventure in the world of GraphQL API federation with a thrilling twist inspired by Carmen San Diego! In this immersive workshop, students will be divided into teams and compete to find Carmen San Diego before anyone else using their GraphQL skills.

The workshop starts off with an introduction to GraphQL API federation, where students will learn about the power and flexibility of GraphQL and its federation capabilities. Then the teams will be formed, and the competition scenario will be revealed—finding Carmen San Diego!

Each team will create their own HQ and extend the federated graph, adding new services, connections, and data sources to gather clues and track down Carmen. They can also try to thwart other teams by giving them false clues. Real-time collaboration and problem-solving will be crucial to stay ahead.

Join us for an unforgettable workshop that brings together technology and adventure, all while honing your GraphQL expertise. Can your team solve the mystery and emerge as the ultimate Carmen San Diego catchers? The race is on!

What is a Virtual Power Plant (VPP) ? : Green tech and the modernization of the grid

Virtual Power Plants (VPPs) are reshaping the energy grid by turning thousands of distributed IoT devices—solar systems, batteries, EV chargers—into one coordinated, cloud-native asset. At Enpal, we operate one of Europe’s largest residential solar fleets and are building a next-generation VPP platform to orchestrate it.

This talk explores what it really means to build a power plant in software—and why developing for IoT looks nothing like typical cloud app development.

You’ll learn:

1. How the electrical grid works (with examples!)

2. How a Virtual Power Plant works—from household solar to market bidding

3. How Enpal’s IoT and cloud systems coordinate to optimize energy use and revenue in real time

4. What design patterns (Kubernetes, KubeEdge, Dapr, event streaming) make it possible to treat 100,000+ homes like a distributed cluster

5. How VPPs make money—through flexibility markets, load shifting, and price arbitrage
