1) I worked to optimize the pictures with alt tags
2) Provided the Developers with the useful assets which were needed to develop this game.
3) Wrote ASO optimized description with keywords.
4) Used all the necessary supporting keyword research tools as well as promoted it on social media.

Here are a few more projects which I delivered to the Gaming Studios
