Talk 1 - Full Stack Reactive

Reactive programming is a niche but increasingly popular approach to building fully responsive systems. One of the most challenging aspects of building responsive systems is dealing with issues of failure and scale while also ensuring near real-time responsiveness.

This talk will dive into what it takes to build a 'full stack reactive' system. We’ll cover some key reactive patterns by demonstrating the concepts using a reference application called ‘Reactive Stock Trader’. We’ll begin with a reactive UI using Vue.js, then dive into key reactive service patterns such as event sourcing and CQRS using Lagom and Java. Finally, we’ll discuss deeper distributed systems concepts like eventual consistency by demonstrating them using a fully event-based persistence layer using Cassandra.

All code examples will be using Java and JavaScript, although the focus of the talk will be on the concepts of reactive programming, and the concepts are portable to many different languages.

Talk 2 - Serverless with Kotlin and Android

Serverless is all the rage lately. This talk will walk you through the entire full stack using an android dating application as our starter project. We will go over serverless architecture, serverless functions, using interactive methods like daisy chaining and persistent key value stores and common serverless technologies like Pub/Sub. We will do all of this with Kotlin and Android
