This C# project serves as an data plumbing layer for some machine learning models. See you hear data the first thing that should come in your mind is Python. Unfortunately this was not the case, and to make it better it is using the .NET extension for Apache Spark. Migrating it to Python makes sense, since it is using rather non-standard technology for the problem, which makes hiring future talent rather difficult. And there are other obvious problems, common in other enterprise OOP languages as well, like mulitple levels of abstraction, inheritance everywhere, inversion of control, again things you do not do in data plumbing. And to futher feed the devil, the original team of contractors/consultants (because who else would use C#, than some enterprice consultant) are going to leave next month.
