Need help finishing a game project (Unity 2D)

I already have this puzzle game in beta in Google play store (Not shared with public).There are a few issues that needs to be fixed before I can publish the game. I need an experienced Unity developer to do the following finishing touches. 1. Optimize game for all screens. As of now the game works well on a 16:9 screen ratio, but on larger screen ratios (like 18:9), the game stretches out of the screen. 2. Set up Google ads for "Rewarded video" and Interstitial Ads and configure the Google ad dashboard for optimum revenue. 3. Setup google analytics. Experience Requirement: - Experience building Android Games with Unity. - Experience in setting up and integrating AdMob. - Experience publishing games in Playstore. Other infos: - The game is done in "Unity 2018.1.2". I prefer it to remain same. - I would love to remove the "Made with Unity" splash screen. Which means, devs using licensed Unity version preferred, although not mandatory. - Once the game is done, share all the finished project files with me. - The right person will receive the future bug fixes and porting tasks to Amazon and iOS. Note: those jobs shall be rewarded as separate tasks through this site.
