When starting out your data career it's hard to know what skills to focus on. There are many blog posts offering recommendations, but none of which are backed by data. "Isn't that exactly what a data professional should do?" thought Luke Barousse. So he made datanerd.tech, a data platform giving real-time insight into what the most in-demand data skills are. One downside of the platform was that it aggregated all data, so you were unable to see how skill importance changed over time. After writing a bit of Python and SQL I made a Github pull request doing exactly that. The feature is now live, so feel free to have a look.
