Upcoming: Strongly typed third-party integrations with TypeScript
Many of us have to integrate third-party APIs, and we cannot trust their documentation. We also need to track when their data format changes. The same is true for integrating our own (or other teams’) microservices. I will show how we do this in an effective and flexible way using TypeScript.
In this talk, I will present my approach to doing this safely with TypeScript and how this enables end-to-end contract testing which I have been using for many years and consider one of the robust best practices we apply basically in all of our web application projects.
This is a very practical, hands-on talk with many concrete examples that will give the audience a clear guide on how to build robust, well documented system integrations.
We leverage NPM modules to version our API definition and create a clear source of truth for all your integrations, be it a REST API, WebSocket or CoAP messages-the same principle applies.
The three key-takeaways are:
- learn about TypeBox and how I use it to make integrations of third-party APIs type-safe
- see a code-example where a frontend-application runs against a mock-API using these types
- get to know techniques to discover breaking API changes through monitoring

Software Quality made this talk happen: push-to-deploy as the means to deal with uncertainty
This talk is an encouragement for developers to trust their skills and tools, but also invest in mastering them.
The three main takeaways are:
- Prioritize writing good quality software that rarely breaks. This allows for better work-life balance and frees up time for self-development and community initiatives.
- Utilize Test-Driven Development (TDD) with a focus on outside-in testing. This builds confidence in code changes and keeps the focus on delivering value to the user.
- Focus on user stories when building products. This ensures collaboration with all stakeholders and fosters a successful software development process.

Exploring better ways to write tests
Video: Updated version, First version · Blog post · Slides
Very often we focus on improving the way we write tests within our test frameworks. I on the other hand invest time into building new test frameworks. Over the last years I have worked on end-to-end testing cloud native applications, which lead to the development of a BDD feature runner. This year I took the idea even further with a focus on coming closer to the goal of living documentation: the test files are now written in Markdown. In addition I started to work on fixing another big issue that we encounter often: our inability to provide good architecture documentation ... what we need is not big, huge architecture diagrams for entire systems (like we get when we use C4, Arc42), but diagrams that are context-sensitive. BDD is actually a great source for these kinds of diagrams and this is what I want to share in this talk.
Key take-aways
- that testing, developing and documentation go hand in hand
- that we as people working on these system need to look at our tools and find ways to improve them
- ideas on how to build living, understandable, up-date architecture diagrams
- new ideas about the features of GitHub Actions, traceability and automated diagram generation

Firmware test automation using real embedded devices
In this talk I am presenting my approach on testing embedded firmware using real hardware.
Testing firmware in emulators drastically limits what actually gets tested and it can quickly become very tedious to mock, fake and set up environments for embedded firmware that needs to connect to cloud services.
I am taking a different route: let the firmware run on real hardware, and test its behavior.
I show how I implemented these tests using Zephyr, AWS, and GitHub Actions. However, this solution can be applied in any environment which cannot be run inside a test runner.

Serverless Architecture for IoT on AWS
Slides: Interactive · Video
Let's have a look how a temperature reading travels an IoT solution on AWS and Azure from the device to the web application.
This is a talk that explains the benefits of serverless in general in why it is especially suitable for IoT applications. It also shows a concrete, open-source example.
It will provide an introduction to serverless in general, and how it is implemented at the different cloud vendors (looking at AWS and Azure, where I have implemented the same application using the respective cloud's idiomatic way), and why it is especially relevant for IoT deployments.

It does not run on my machine: Integration testing a cloud-native application
In this talk I will take you through the challenge of testing a cloud-native application. I will cover the challenges when developing solutions on top of serverless components which you cannot run on your own machine and how I designed a BDD driven approach to run the integration tests.

Motivating developers with purposeful work
I work at a company where we decide on our own, when how and on what we work; I have full control over my life. We believe that working in a so-called network organization, without central leadership, is the only sensible and sustainable way to run a business. But what does that mean for managers if you no longer can assign work to your team? New skills are required and in this talk I want to give a glimpse into the future of tech-leadership and what is need from you to build a joyful workplace for team.

TDD vs. Velocity: Testing for start-ups and other organizations with fast innovation cycles
These days, when every new project is a start-up, we need to run software that is both robust (because there are customers already using it) and open for change (because we are constantly adding new features). This provides a challenge for applying TDD.

Having remotes on the team enables you to hire for talent and not for availability. From my recent positions I learned that it is critical to encode remote work in every team members work habits-even if they are working on location. This talk highlights the issues that arise when teams or not co-located and how to deal with them.
