I'm using firebase as it was best choice for single developer application. No need to worry about server side parts, and a healthy free tier means no need to worry about few mistakes you make about architecture. Sometime I worry as my app constrained to single supplier, but I doubt I would be large enough to actually worry about it, and when I will be that big, hopefully I would be afford to hire to move to better solutions or optimise to better suit to existing platform.
