Works
BookViewer 3

My first UWP app is BookViewer. It is simple CBZ/CBR/PDF viewer with bookshelf feature, and soon became my most famous app with 30+k users. It was good app, I've been using myself, but I knew there's lots to fix.
So I made BookViewer3. It is based on the 1, but have completely different user interface. The 2 failed by the way. I know it's very very good app, but it is also true that there's more I can do.
RhinoArchitecturalLibrary

I've been involved in 3D modeling stuff by 2017. It's not what I do these days, and not all of my work is open source, but RhinoArchitecturalLibrary is one thing I can recommend for sure. If you have some experience in Grasshopper and you're here reading this, I'm sure you know what C# component is. RhinoArchitecturalLibrary is codes for that. It helped me a lot, and it might be the case for you.
CellTower is one of my project which used the library. All that I had to do is to write <100 lines of codes and here it is. The skyscraper above is the result.
