ARCore expert needed

Hi. I am looking to hire an ARCore expert who can help me in a module for my AR application. I am actually making a drawing (random lines in the camera view). The points of these lines are stored in my database. Now I need to fetch those points from database and want my app to re-draw those line which i drew before automatically on the screen whenever I re-launch the app. so basically i don't want my drawings to disappear on closing the app. Can you kindly help me on this?
