Why I am committed to joining Toptal.

As I understand your needs, you are first and foremost looking for someone who can work like freelancer. As you’ve said you need someone with a strong background in IT software and Mobile application developer. This is where I’ve spent almost all of my career, so I’ve chalked up 6years of experience exactly in .NET and PHP. I believe that I know the right contacts, methods, principles, and successful management techniques as well as any person can in our industry.
 

You need someone to give a new shot in the arm to mobile software development, someone who knows how to develop android application. Here, too, I believe I have exactly the experience you need. In the last three years, I’ve done 2 android applications and live on play store
