    Fullstack Developer
Senior Software Engineer (Python / Django)

Python developer who is specialized in web development with Django. I started my professional career when I was 20 (2012). Some of the interesting areas I was working in are, inter alia, face recognition, gathering information from pictures, comparing faces on images.

During my backend work, I was also DevOps, it's not my main area of competence but I've got some experience with Docker, Vagrant, Ansible, Fabric, AWS (S3 and EC2).

Backend development is really important for most of the projects but really often backend without frontend is worth nothing. That's why I decided to start working on this side of the project as well. I tried to implement applications using AngularJS (1), ReactJS and obviously HTML and CSS, I'm not so good at it (especially with styling) but I'm still involving to be better frontend developer and eventually become full stack developer.
