I can work on these types of API. I have personally designed, wrote the functional specifications for APIs that work like Twitter, PayPal API for Cisco, Western Union, GM, Chrysler, LexisNexis, American Express etc. This do need painful times to understand what this API should do, for the customers who intend to use them. But since there were continuous changes in management and people who lead these teams couldn't really were able to handle pressure, and were blocked,
I wanted to help them from outside, so I moved out to be a independent freelancer. I believe I will be able to explain to you better on skype than here. I see that mostly employers here are sourcing agents who really don't understand anything about internet based business and do not know how capitalism works. I am very serious person, who has to pay around 580 USD for a house in India. So I am not wasting time around here. If you are a real genuine person, I would suggest we discuss and see if we can explore opportunities including tapping into local resources, if you know how it works. I can handle coding, code reviews, interaction and many other thing. Let me know.
