I haven't taken an online course in CS for almost a decade. Shifting interests. Changes in the business structure of MOOC's...Basically since they stopped being called "MOOC's" and became closed down.
Helerstein's CS186 video lectures (Introduction to Database Systems, 2015) are probably the most informative CS-thing I have experienced online:

But of course, it is not an online course. Just course lectures online.
It's informative because the problems - IO, optimization, caching, concurrency, partition, etc. are all right there in ways that require engineering (i.e. theory alone won't get you to the required scale). YMMV.
Good luck.

Stanford's course on writing apps for iOS is wonderful. I took it years ago. Now it has moved on to SwiftUI. I think the previous versions on Objective C (the one I took) are still available.

Working. Narrow down your interest, pick an udemy course, find an open source project in that area to contribute
