* Moritz Wilfer “How to design your application to avoid your cloud provider as a single point of failure?”

Payworks has very strict SLA requirements with their clients. We came a long way to make our system reliable enough to keep our contractual SLAs. One of the learnings was that even the most reliable cloud provider can break and is a treat for your service SLAs. I will present the path we took and take to mitigate the dependency on your cloud provider for your SLAs.

Moritz Wilfer is System Architect for the backend development at Payworks. He studied computer science at TU Munich and Georgia Tech (Atlanta). Payworks backend teams are currently working on the transformation from a monolithic to a microservice architecture. Moritz has a strong background in databases and performance testing which helps him in his daily work of architecturing a resilient, performant, and highly available payment cloud.

* Grzegorz Dyrda “Introduction to Kotlin”

In this presentation I try to show You the biggest advantages (in my opinion) of a great programming language - Kotlin. I use it for two years now, and I simply love its readability, elegant solutions of Java’s biggest issues, and vast amount of features that we won’t see in Java anytime soon… Let’s add the fact that Google announced Kotlin as an official language for Android, and gained dedicated support in Spring 5.0, and the situation is getting interesting… ;)

Grzegorz had been coding for as long as he remembers. He has already done desktop applications, backends, frontends, embedded, banking and payment systems and other wonders ... However, it's only on mobile platforms that he feels like a "fish in the water". For a few years he has been creating and selling his own apps, and earning his bread and holidays in Canary Islands;) Grzegorz is great enthusiast of Kotlin, reactive programming (ReactiveX), and recently also JavaScript (sic!), React, serverless and others :)
Privately - he makes plans for a millionth empire, runs a blog (blog.geekydevs.com), he likes hiking, plays the guitar, reads …
