Vanilla Javascript Webapp (Front-end only, just 2 screens)

Hey, I need you to build a clean vanilla javascript webapp.
The design is ready in figma.

I quickly list the technical "challenges"
- light and dark mode
- upload a photo & convert to 120x120 base64 compressed
- ask for camera and open in fullscreen
- a tab-view controller
- a qr code overlay

That is already it, additionally there are some simple things, quite a bit of CSS, but overall it is a fairly simple task to solve.

I need this asap, if you can solve it in less than 2 days, that would delight me !

Edit: I added a screenshot which shows the size of the project.
