As I work on this tool, there is a lot of boilerplate and research needed. To keep me motivated, I plan to release everything not related to the core product, as a polished open-source subproject.
This is an easy win, since I have to do the work anyway, and it feels good to release something.
The first release is an API client for a financial aggregation API. It is written in C#, and published as a NuGet package.
