Who am I?

Hi, I'm Roelof Jan! I'm a full-stack developer in Groningen and I enjoy a challenge. I'm currently working as a lead developer at Tubber, a platform to facilitate C2C, C2B, and B2B boat rentals all over the world. I found my challenge in learning and applying new technologies to solve increasingly complicated problems. As a full-stack developer, the problems I'm trying to solve are of a very wide nature. The problems range from cutting the boot time of a website in half to coming up with ways to build the platform in such a way that real-time availability of boats and booking data is possible. Even when you're working with a system that pulls its data from 5 to 10 different sources.

Do you want to know more about my skills?

I've put together a list of technologies I'm comfortable with using in production. These technologies include, but are not limited to, PHP (Laravel), JavaScript, TypeScript (Angular, React.js), and Golang. You can read more about my skills by reading about "My tech stack" or by having a look at my CV.
