Hello, I read your job description carefully.
As a professional dev, finishing task on timeline is my best personality.
Your work is really interesting to me, and now I am prepared for you.
I already have built many android app using ionic and react-native.
And then I developed various app using java code such as android, iPad, ADT dev framework, unity3D, C#.
I can use various kinds of themes and also I have rich experience in upgrading the java version and developing new modules.
From my past work, I think I can be the right person you are looking for.
Looking forward to hearing from you.
Thank you.
