Join us for an enlightening session on the topic of breaking up monolithic architectures into microservices. Discover the compelling reasons behind this approach, explore the numerous advantages that microservices offer, gain insights from examples of monolith splitting, and gain valuable knowledge about the common challenges and issues that arise when working with microservices. This talk is a must-attend for anyone seeking to unlock the full potential of their architectural designs.

Our clients don't know what they need.

This happens because no one can foresee the future.

Requirements will evolve and change rapidly over the lifecycle of the project. That's why we need to refine systems constantly.

We can keep building and discarding prototypes, but it's extremely costly.

Often we can't afford to rewrite everything from scratch only because some new domain insights were discovered.

This eventually leads to a mismatched model.

Is there another way?

We can focus on domain only and refine our model through examples until we find the right conceptual contours (http://ddd.fed.wiki.org/view/welcome-visitors/view/conceptual-contours).
Each such iteration of the model is a kind of experiment challenging the upfront decisions.

During this presentation, I'm going to show how you can use example mapping combined with business-oriented TDD to be able to run rapid experiments directly on the domain model without the need to rewrite the system again.

Speaker Bio

I'm a software architect with passion for creating great products. Domain-driven design & Test-driven development are some of my favorite tools. My code is clean and easy to modify, thanks to the modular, loosely coupled design achieved by continuous TDD iterations backed by a deep understanding of business requirements.

I'm also a professional consultant and trainer. In my free time I create online courses and write articles about software development, DDD and clean code.

Talk Information:

Luke Barge & Noah Lawrence - Functional Domain Modelling in Kotlin

In this presentation, we investigate the ways in which we enhanced our production code by employing functional programming methods to improve our domain modelling, ultimately making the code more robust and simpler to manage.

Andrey Breslav - Shoulders of Giants: Languages Kotlin learned from

New languages are inspired by existing languages: every generation learns from the previous one. Kotlin is no exception: its design is based substantially on the designs of languages such as Java, Scala, C#, Groovy, Python, Nice, etc. This talk will explain which parts of the design are inspired by which languages and what Kotlin does differently in each case.

Speaker Bios:

Andrey Breslav

Andrey was in charge of the design and development of Kotlin since its conception in 2010 and till Kotlin 1.4 in 2020. He co-authored the core language design with Maxim Shafirov in[masked] and lead ultimately assembled and lead a 100-strong team. Andrey presented at numerous events including KotlinConf, Google I/O and Devoxx and co-authored the Kotlin for Java Developers course on Coursera. Aside from Kotlin, Andrey co-founded a successful online psychotherapy platform Alter, taught programming and computer science to college students and promoted diversity in IT.

Noah Lawrence: Senior Software Engineer

Noah has been working with Kotlin for two years as part of the car finance team at Zopa. Previously, he worked with Java at a fintech start-up and a technology consultancy. Noah is a big fan of the Arrow library for functional programming in Kotlin and has been using this extensively in his work at Zopa.

Luke Barge: Software Engineer

Luke, with 5 years' JVM experience and 1.5 years in Kotlin, is passionate about functional programming and how it can be used to create more maintainable and less error prone software.
The LJC would like to thank Zopa for hosting this event.
