While studying physics, I found computational physics especially interesting: How to verify theories with experiments? I went to a 3-day course “Deep Learning from Scratch” and this triggered my interest in data science. At Allianz Technology, I started as an intern in the functional architecture team, then worked as a functional analyst - which is quite strange to be the first job in IT! But one year later, I moved to the Business Analytics Team as a Data Scientist. For an important project, it was necessary to work with Spark, a Big Data framework – after months of self-learning and debugging, we successfully accomplished the project.
