Hi! I want to contribute

I am experienced developer and someone who for many years have been a big fan of visual flow type programming and when I came across node-red a few years ago I was impressed with the tooling and capabilities of it. My background has been more Java based over the years but JS has been prominent in my development and most of last year I was working in node and Angular. I am looking for an open source project I can contribute to but it has to be one am passionate about. Can anyone confirm the best way to help contributing to this project and make a suggestion on a bug or a small enhancement that would be a good place to start. I would class myself as a full stack developer but I really do like the front end stuff so any UI bugs or enhancements would e ideal for me. Thanks!
