**===Topic===**
**1st talk: Breaking Things to Build Better Apps**
Is your application truly ready for production? Don't wait for a real incident to find out!
In this talk, we'll dive into the world of Chaos Engineering, where we intentionally introduce failures to learn how our systems behave.
We'll explore fault injection and discover which tools can be used to simulate real-world failures, from infrastructure issues to application-level faults.
You'll learn how to proactively uncover weaknesses, allowing you to improve your application's reliability and avoid costly production surprises.

**Speaker: Stefan Sepin**
Stefan is a software engineer at andamp GmbH with a passion for building high-quality software. For the past five years, he's been using Kotlin to build both Android and enterprise applications, working on diverse projects in the e-health and public sectors. He's particularly interested in software quality and DevOps, focusing on creating efficient and reliable systems.

**2nd talk: 12 (or more?) overlooked API details that can get you in trouble**
API design and implementation are skills that are usually treated as just parts of mastering an implementation language like Kotlin. Poorly thought-out API decisions or APIs driven by implementation framework defaults can lead to maintainability, security or performance problems that are hard to fix once the APIs are already in use.
In my talk, I will show real-world examples of APIs that work well at the beginning, but can be the source of unexpected problems later.

**Speaker: Marián Varga**
Marián Varga is a freelance software engineer with over 20 years of professional experience. In his work he connects software systems as well as the people involved. He publishes his thoughts on his blog [dastalvi.com/blog](http://dastalvi.com/blog "Original URL: http://dastalvi.com/blog.
