Functional programming styles have some advantages, like predictability and great debugability. Those rely on well-defined patterns that implicitly avoid that you end up shooting yourself in the foot. The newly proposed JavaScript pipe operator comes without this protection and has a good chance of introducing hard-to-understand code and bad bugs. Here's why.

One of the more difficult decisions in software development is choosing between specialised and reusable solutions. So let us look at both and see if we can understand when to use which.

For a few years now, discussions rage on between two seemingly different programming paradigms: functional and object-oriented. But what are the reasons some people prefer functional and is there a clear winner?

With methodologies like microfrontends and atomic design, and techniques like module federation and import maps, we steadily walk in a direction where our frontend is composed during runtime. And yet, we lack the tools to have cheap tests that ensure that we won't break the system. Let's take a look at a possible solution: contract tests for components.

Team building is often seen as a tool to help a dysfunctional team to get back on track. And just as often, it fails to achieve this goal. Let's take a look at what the team needs and how I as a leader can help.

Microfrontends is a term that has come up in recent years, but in reality, we have been doing it for decades. Let's take a look at my journey and the lessons I learned on the way.

I send out an anonymous survey twice every year - but never during that time were we facing a pandemic. Let's take a look at the impact that this has had on my results.

Software created in Germany never had the same flavour as cars. It's actually more of a smell. And this smell is gradually leaking into the other products. But what can we do to change that? I have three ideas.

I'm playing around with software since I was 8, and was lucky enough to make this hobby my work.
I was founder of two companies, and worked with some german and international companies as Software Developer and Manager, most notably Microsoft, AutoScout24 and 1&1.
I'm a dreamer, who loves to dive into a chaotic, complex environment finding the best way to optimize the system. I'm a coach, helping people to develop themselves, and work in a group. I'm a manager, who is striving to create teams that do not require his management. I'm a developer, who loves to write code and make the world a little easier. I'm a dreamer, hoping to improve the world.
Also I'm into sport, married with children and love my life.
I'm a regular speaker on conferences in Germany, mostly around the topics organizational development, agile and teambuilding (i.e. in 2017 on the ScrumDay) and successful DevOps and agile implementations using bottom-up change processes (i.e. in 2017 DevOpsCon and XP-Days). I published the article “Reinvent your workplace” in the iX in 2016 with a collegue at 1&1 following a talk on the continuous lifecycle conference around how to change a department in both technical and organizational dimension.
