Profile

About

I am really excited to see how technological and scientific developments will shape our future and I want to be part of it myself. Alongside school, I work as a software developer at COSMO CONSULT, where I gain early experience in professional software development and contribute to projects in the innovative field of computer science. Through refereeing football matches I constantly train my ability to lead under pressure and make fast, responsible decisions. I love to constantly grow, learn new skills and face new challenges by placing myself in environments that push me beyond my comfort zone.
