A docker-composed picture frame

Cloud Based dockerized raspberry picture-frame with NextCloud and Balena Cloud

How many docker containers do you need to create a picture frame for a raspberry pi? The answer is 3, obviously. With BalenaCloud, WPE and nodejs we are creating a simple random image slideshow in the most complicated and awesome way.

DNS with integrated AdBlocking in the local network

There comes a moment in every local network where you have to remember 255 IP Addresses. Which is easy. The hard part is remembering what device is behind what IP. Domains can come to the rescue, and why not creating an internet without Ads while we are at it?

Homecloud with RAID 1 for 300 EUR

Building a HomeCloud

My family produces too many videos that (for unknown reasons) we want to keep. As cloud storage is expensive at Terabyte level, and I love building things, I took an alternative approach to have my own fault safe 3TB HomeCloud at ~300EUR.

A helicopter needs an LED. Always.

Improving a toy helicopter

Sometimes, my kids expect a little more of their toys then they get. Luckily in this case, with an LED, a button, a battery and some cables, this can be fixed.

What is it I do?

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.

Who am I

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.

More

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.
