Hi there,
I am Aagam Jain and I have 5+years of experience in android development. I saw your requirement that you want to make changes in the existing android app and I am very much confident that I would be able to develop those changes for you.
I have worked on various complex android apps and have successfully completed them.
I assure you that you wont feel disappointed by my work and would deliver you the best product.
Looking forward to work together.
Thanks,
Aagam Jain
