Radu Pastia: I've been working with Hadoop two years ago, when I started the Big Data Team at Avira. At first I was oriented more towards the operations side - sizing and setting up our new Hadoop cluster to run smoothly. As our setup stabilized, I started delving deeper into data science and machine learning. I have been coding ever since I had my first home computer running BASIC and my background before Hadoop is in backend scripting for web-based applications.
