Diese Anzeige ist nur für angemeldete Nutzer möglich.

I am a passionate Python developer with over 10 years of professional experience. I mainly develop applications in Django, but as I graduated in the field of computer science and neural network, I started to gather experience in that area as well - this includes image processing for object detection, object segmentation and depth map reconstruction.

I think the best way how someone can grow his or her skills, is being part of a team. With that said, I love to learn from each other's experience, as well as I, like to share my knowledge to help other's to solve emerging issues or to evolve their skills.

Originally, I came from languages like Pascal, PHP, C++ and Java and got hooked to python by the accessibility and the Open Source community. As being part of this community, I do publish some of my work as Open Source as well.
