The talk will give a quick intro into Kotlin for Web via KotlinJS. It will speak about the ups and downs in comparison to Typescript. It will go into the idea of Kotlin Fullstack and what this can mean for your codebase. And of course it will ask if it is something you want to use in production.

Jetpack Compose is a declarative UI framework for Kotlin and Android. Jetpack Compose makes it easy to describe your UI graph and build composable UIs.

On the other hand, GraphQL is a declarative language for your Data. GraphQL makes it easy to describe and query your Data Graph.

Sounds like a perfect match!

In this presentation, we'll take a look at the current mobile architectures and how they differ from web architectures.

We will dive into cache, offline mode and error handling and investigate how GraphQL can help mobile developers build more reactive and robust UIs.

Using real life examples from the GraphQL conf 2025 app, we well discuss patterns such as colocated fragments, optimistic updates, subscriptions and see how they fit in the mobile app development cycle.

While it will use some Kotlin, most of the examples can be applied to iOS and/or any other mobile platform.

If you're a web developer, I'm hoping to give you some talking point to start the discussion with your mobile teams. Let's unite frontend developers!

Join Oleksandr as he explores the world of micro frontends and the advantages and disadvantages they offer. During the talk, Oleksandr will provide an overview of the benefits and limitations of micro frontends while showcasing an example of migrating a monolithic app to a modular application in a monorepo with micro frontends. Attendees will gain valuable insights into each stage of the migration process, as well as a better understanding of how micro frontends can offer scalability and flexibility in their own development projects. Don't miss out on this informative and engaging talk!
