Everything is possible, but we can Not use whats app api (as whats app does Not give).
Please start chat to discuss.
I have 20 years experience in Web and Software development.
In our company, we have below types of experts :
=> Web designers
=> PHP developers
=> Ruby on Rails developers
=> .Net developers
=> Android developers
=> iPhone developers
We have just started expanding our horizons through this website, till now we were getting work by reference, so you may think that we have done very less project, but it is Not like that ;)
This will be a start of long term relationship (as we are sure about quality!).
