I want an Android Developer To Do Some Changes In my App.

Must be 3-5 Years Experienced in Java.
Known to handle API Calls.
My app is in Java and the Backend is In SQL (Laravel Admin panel).
I want some new integrations and bug fixes which will hardly take 5-10 hrs for an experienced developer as I will explain the exact work in detail.
The developer must be experienced in placing ads (Interstitial, Native, Rewarded, etc).
