Hi there!

My name is Kasper Due and I’m a Frontend Developer from Denmark.

I started my as a backend developer working with C#/.NET Core, MSSQL. Then I was introduced to Angular and that was my gateway to the frontend world without and all the framework and libraries made with javascript
Now I work as a frontend developer at Nemlig.com where my daily work is spent with using technologies like angular, sass, typescript. I really like to work with React and next.js which this site is also created with. Someday I will take the time and learn vue and dive even more into svelte.
As a side project i'm working on tempody.com - Where you can easily create and store all your running trainingplans.

user experience is the key

Working with frontend development, I focus heavily on performance, smooth animations and pixel perfect design, which will overall create a great user experience. I always approach my work as a product that exist in a business context, and will therefore focus my work around meeting deadlines and the managements KPI’s.


Passion for running

I'm a passionated runner always striving to get a new PR . I’m currently training towards the some marathon in 2021 When the coronavirus will allow it. I find it necessary to get in some exercise on a daily basis since the job as a developer is mostly spend in front of a desk.

My goal is to run a sub 2:45, and create a personal best (PB). My current PB was set at Berlin Marathon 2019 with a time of 02:53.

occasionally i post some running updates on instagram. Running is a big passion of mine, and I also follow all the new science and news in the running community, and my big goal is to run the Boston Marathon.

If you have any question to me, don’t hesitate to get in touch with me. My doors is always open!
