I have over 8 years of experience and have worked for IBM and Accenture. For Accenture, I have worked on projects in which I integrated twitter tweeting functionality to an enterprise software. I have also created a software in which facebook interests such as movies are downloaded to the software using facebook graph apis. I also understand APIs, and web services in general and how to use them. I'll have to work out the details with you but I can surely complete your project and integrate ebay using ebay APIs to your software. Let me know if you have any clarifications related to my expertise or plan for project completion.
P.S. I'm bidding low as i'm coming back to freelancer after a long time and want a new project. All I want is a good testimonial from you, rest assured, i'll make you happy with my work. Just take a look at my ratings.
