How to position a circle behind 2 overlapping sections

Hello everyone!
Before I start I want you to know that I’m not a webdesigner so sorry If this is kinda basic…
I need to translate this Design into Webflow and I’m struggling at some points:
This is the Design


After the smartphone section I need to position the circle behind the white font but also behind the div before and after the section. I really fail on this task right now ^^’ Maybe you have advise for me?

Also the little robot at the top is randomly floating somewhere when I resize my window. Haven’t found a good solution to position him like in the design either…
