Welcome to “Inside Wercker,” where we introduce you to one of our team members. This time we’ll get to know Mies. You can follow him on twitter



Who are you and what do you do at Wercker?

I am the Founder and CEO; this means that I do general operations, oversee product development, hiring and fundraising. Sadly I find that I code less and less (much to the delight of the development team) and do occasional design work (pick colors).


When did you know that you wanted to be a developer?

Its always been something I did. I started programming in BASIC when I was a kid and kept on programming all through high school. I have always been a bit of a multi-tasker, so I did not fully commit to hardcore development but always opted for a bit of business training on the side.

Even though I have always been a bit of a hybrid, when it came to my interests within development I have always had a soft spot for distributed systems.

In many ways, I am a product of my time. When I was studying at the Vrije Universiteit (VU) -which has a great and well-respected computer science department- Werner Vogels (A fellow Dutchie and VU almuni) just published the Dynamo Paper which quickly became compulsory reading at the various distributed systems courses I was taking. At the time there was a lot of noise around cloud computing and distributed systems (microservices wasn't even a thing), and I guess I love a bit of complexity and problem-solving so fell right into it, eventually providing the inspiration for Wercker.


What attracted you to wercker?

The fact that it was my idea :)


What software do you use?

As a CEO I spend a lot of time in my inbox and calendar :(

I use Shift for managing the above with my other calendar and Inbox accounts and miss Sunrise on a daily basis.

I use Slack for group chat and Quip for design documents and collecting thoughts (also spying on the rest of the company). When it comes to designing, I use Sketch and Framer.

I am both an iPhone and Android user (also a project Fi guy).

I use Amphetamine to keep my screen alive, I'm a big fan of Golang, use MacOS, and occasionally I fire up iterm2 and Vim for when I do need to code. I then build this hypothetical code using the Wercker command line interface that builds a Docker container.

In iterm2, I have z shell zsh with pure theme, and on Vim I use tomorrow night color theme. Homebrew is my package manager of choice. Hardware-wise I use a spacegray 15” Macbook Pro and a Das Keyboard Model S Ultimate for my aggressive typing. At home I work on a 27” iMac with a 5K retina screen and a Das Keyboard 4C Compact for my less agressive typing. 

Rotring is my brand of choice for pencils and pens , specifically the Tikky fineliner and Rapid Pro ballpoint plus mechanical pencils.I use Spotify and Soundcloud for music along with my AIAIAI headphones.

What side projects are you proud of? 

No time for side projects. To take my mind of things I play some tunes on my sunburst Epiphone acoustic guitar.


Where would we run into you when you’re not sitting behind a computer?

When its nice outside I hangout on the Amsterdam terraces having a beer with my friends. If I'm not there you'll find me close to any exit in the front of the plane (left hand side window seat) on my way to SF.
