I have been writing code for more than two thirds of my life, mostly for scientific computing and data analysis. In the past couple of years, I have worked on a range of different data science projects, all using Python at their core. During this time, I repeatedly was tasked with making data usable by joining multiple sources into a clearly defined data model. Once you have done that, it is amazing how much real-life value you can generate with little more than a bit of statistics and visualization. The world is full of underused data, let’s change that!
