Curious what you mean by this, as it's overall one of the more polished products I use on a regular basis. Hasn't always been the case, and the Android app still does some weird UI things, but generally the product is solid and a pleasure to use.
"Whole stack could be handled by one guy" - comments like like this and similar others ("I could build Twitter in a weekend", etc.) strike me as unproductive.
For example, Netflix consistently forgets what I have seen and if I don't watch the ending credits it thinks I haven't watched an item and suggests it in the continue watching section. There should be visual indicator on what I have watched, and if there are unwatched episodes in series. Now I have to open it and go to the episode list, which is unreliable. Also, starting video playback is too slow. It's not possible to open items in new tabs. There are no keyboard controls.
