Zoom effect image Get Coordinates - competition system

We are looking for a person to help with an already partially built project written on Symfony who is good with JS, handling positions (coordinates) from a photo.

We are modeling the project on https://www.botb.com/prizes/cars#!/.

In short,

- pixel typing solution should work on mobile devices and computers

- as you can see, the workspace in the browser can have a size of, for example, 800x600 while the photo that is added there is 3000x4000 px, and it is by using the ZOOM effect that we can select one of the pixels

- a single pixel should be marked on the photo - be visible under a magnifying glass

- a single pixel can also be removed

- a single pixel is ultimately a lottery ticket - multiple tickets can be purchased
