Love your work. I have a Poet-Master 8 on 1020 and a Vitamin Inventor she is still on Exceptional 7 earning 900 I'll let you know what she earns if she makes it to Master. She is 43.Perhaps you could add these to your list. Cheers

Seriously! The highest I have ever earned on a masters level is 690, mostly from designers and inventors. Where did 1020 come from?

Neither i saw any salary higher than 690

It differs if you are on a PC / Mac or on a mobile. PC salaries are roughly twice those on iOS / Android.

What's a QA engineer? Can they still build rooms for free as a master level like a regular engineer?

Edit:
Omg. I googled it (like I should have done in the first place). No, clearly this is not the same as a regular engineer. * Face slap * Please, someone learn from my mistake, and don't pick this career if you're looking to build rooms for free! * sigh *
