Full Stack Web Developer with a passion for the front-end

In my internship and first job at Dovetail I started out as a front-end web developer and slowly evolved into a full stack web developer. This allowed me to gain experience across the full stack of web development. In the coming future I want to focus on and specialise in the front-end part of web development, because that is what I enjoy the most.
