Sometimes my friends ask me why I have decided to become a data scientist. My answer is almost always short: 'Because it is the most interesting job in IT nowadays'. I have a strong mathematical background from university and I have always wanted to work on unique solutions which bring something new to clients. My first job was an ERP (enterprise resource planning) programmer where I learned a lot from experienced people but I felt that I wanted to try something more interesting than regular programming. That's why I decided to change my position and applied for a data science job.
