Hello Sir,

I can resolve your issues without affecting your old functionality. I can start it right away just after your confirmation.
Moreover, I can work on both platform that would be grateful for you because you don't need to hire platform dependent developer.
I'm having 7+ years of experience on mobile technology (Android & iOS) and developed around 70+ applications which is almost on play store.
I can play very well with Java, Kotlin, Objective-C & Swift.
I am also looking for long term collaboration.
Lets have a quick discussion fore more info.
Thanks & Regards
