About Myself

My name is Kevin J., also known under my pseudonym nX_. As an experienced full-stack developer, I began obtaining my skills in various frameworks, languages, and programming systems at the age of 12.

At 17, I moved to Denmark in 2012 and founded my own software development company the following year. Throughout my career, I have been involved in numerous projects and have been able to establish valuable connections with studios, other developers, and designers. Moreover, with my company in Denmark, I successfully implemented numerous projects for both companies and private individuals.

In 2022, I decided to return to Germany and end my self-employment in Denmark.
