I enjoy simplicity, in everything. Unnecessary complexity is evil. Have a look at my WordPress plugins.

About Me



I am Danny van Kooten, a young and passionate Dutch guy with loads of experience building web applications.

In the past, I worked as a freelancer on various projects, ranging from small scaled blogs to pull-powered web platforms.

Nowadays, I build great web products with my company 12notions which will help you build your online business. The most prominent example of this is MailChimp for WordPress, with close to half a million downloads.


My first apps

At the age of 13 I took a JavaScript book with me on a family vacation. With no computer anywhere near me I tried to grasp the concept of what I was reading and dreamed about all the cool stuff I could create with this gained knowledge. A few weeks later I developed my first application in a very outdated programming language. For those interested, it was a “love calculator” that always scored 100% if you entered my name.

Another few months later, I developed an application for the Texas TI-83 calculator while in class. The application helped you solve the Pythagoras formula and became extremely popular at my local high school.

I loved that feeling and was hooked on programming ever since.

Studying Computer Science and starting as a freelance web developer

I started studying Computer Science when I was 19. A few weeks of classes later, I was bored. I found that I could learn at a much higher rate by consuming the endless amount of online resources on the subjects.

As a result, all my free time was spent reading and playing around with code. As most students, I needed money to cover the bills so I started taking on some freelancing jobs. In the 2 years that followed, I converted well over 200 PSD’s to full-fledged WordPress themes .

During those years, I released my first plugin for WordPress called “Newsletter Sign-Up”. At the time of writing, it’s downloaded nearly 200.000 times.

Besides nerding around..

When I’m not nerding around (not that often…) you’ll often find me visiting music festivals, eating, having a drink with friends or practicing sports, particularly mixed martial arts (MMA) or calisthenics. I’ve competed professionally 5 times (amazing experience) and participated in various Brazilian Jiu-Jitsu (BJJ) tournaments.
