Jettro Coenradie likes to try out new stuff. That is why he got his motorcycle driver's license recently. On a motorbike, you tend to explore different routes to get the best experience out of your bike and have fun while doing the things you need to do, such as going from A to B. In the past 15 years, while exploring new technologies, he has tried out new routes to find better and more interesting ways to accomplish his goal. Jettro rides an all-terrain bike; he does not like riding on the same ground over and over again. The same is true for his technical interests; he knows about backend (Elasticsearch, MongoDB, Axon Framework, Spring Data, and Spring Integration), as well as frontend (AngularJS, Sass, and Less), and mobile development (iOS and Sencha Touch).
