I really like Redux, the principles upon which it is built, and the clear separation of UI and business logic it facilitates, but I don't use it terribly often for the sole reason that I think it really shines when an application has large complex state, and nothing I work on day to day at the moment has state complex enough for me to need Redux. So the opportunity to work on a large scale app that uses Redux is something I would be very excited about.

I am comfortable with the functional principals Redux is built on; I know why immutability, and pure reducers are so important. I have built a couple small todo style apps to get familiar in the past when I was learning React and have used Redux Thunk in the past. Recently I got a chance to play with Redux Saga a little bit as I was trying to sort out a solution for loading authenticated data server side when rendering a React app. The challenge was that I needed to know when all the API calls were finished which I don't think was possible with observables, and Redux Saga has an END channel that works very well for that exact purpose. Being able to declaratively write async logic using generators is also something I thought was a cool idea, and I would love an opportunity to use Redux some more and learn more about it, as I really have just scratched the surface.
