Here you will find my resume...

I love to code and to challenge myself. It is my passion that happens to be my work as well.

My first code dates back to times of Commodore 64. At that time, it was mostly just copy-pasting from the coding book and playing games, but it was so much joyful and exciting. Later on, I could do more advanced applications in Pascal on Intel 80386. Those experiences raised my interest in computers and programming. And till these days it never fades out.

Bad code even though works, it usually causes more damage in the long run and stalls further development. Therefore, I find enjoyment whenever I can come with elegant solutions to a challenging problem. I focus on clean code that does not need comments and on architecture that supports its evolvement. And most importantly on solutions that bring values to customers.

I am an open-minded person that likes to see things from different perspectives. One can learn a lot when the mind is open and ready to listen to the opinions of others. I deeply appreciate being surrounded by passionate and knowledgeable people.

I share my knowledge and I am even more enthusiastic to learn from others. Sharing own knowledge is the best way of learning. One must organize thoughts and gain a deeper understanding of the subject before explaining it to others. Furthermore, I am always keen on obtaining domain knowledge from domain experts.

TL;DR I am a great developer and colleague ;)
