Create for the user, not the client
Creating great user interfaces is all about having the user in focus. The users most valuable asset is time and that is why building a fast loading and intuitive interface is key for getting a high conversion rate.
I work as a web developer at Capgemini. I design and build web applications you'd want to use, with focus on mobile first, performance and usability.
At Capgemini I've been responsible for a community of practice in Frontend development and I have functioned as a stream lead for the frontend track in our graduate program.
