There used to be this awesome resource called codepath. They took a developer from tutorials to actual intermediate/senior tier. It was a bay area hands-on thing but I would frequently watch their recorded videos or their online documentation. They still have some material up but a lot is gone (e.g. videos) and I am doubtful if things are up to date. But yeah .. that was awesome and I still point my engineers to what remaining resources they have left online.
