Professional Profile

Outstanding software developer with over six years of professional experience. I am receptive to new ideas and willing to be involved in a wide range of projects. Although professionally I'm working as a software developer, my educational background includes physics and mathematics. I improve these skills and knowledge by continuously self-educating myself outside of work, for example by taking Coursera courses. I mostly develop back-end parts of the projects I'm involved with occasional work on UI. I have very strong interest in machine learning and spend significant amount of my free time playing and learning with the different technologies in the field.
