Kjetil Høybråten is a Tech Lead at Sikt where he's working on FS, our Student Information System. During the last few years he's been hard at work replacing the old APIs with GraphQL. He'll be sharing what's worked well and what's been painful during this transition.

We've been experimenting with how Claude Code can help us migrate the functionality in FS-klienten (our legacy PowerBuilder application) to our new frontend FS Admin. The results are really promising and indicate that if we manage to use Claude correctly, this is a game changer.

I'll demonstrate how a team at Sikt used Claude to analyze screens in our legacy application, then plan and finally extend our existing GraphQL schema with the neccessary changes for this screen to be migrated.

At LEGO.com, we have made great strides in stabilizing development cycles in our GraphQL gateway. We'll discuss the issues we used to have, how we used community tools to fix them, and where we're looking to go from here.

Darrell has recently spent a lot of time in and around the extensible GraphQL validation system. What started as a simple rule to fill a gap in the default rule set, soon turned into a plethora of custom rules to validate every detail of schema business logic in the Neo4j GraphQL Library. He will walk through some basic rules, and demonstrate how the system has been used to implement more complex logic.
