Hi ,
I'm an expert in developing betfair applications (bots) using their free and paid APIs. I have developed over hundred of betfair applications for markets like horse racing , soccer , tennis , cricket , greyhound..etc using betfair APIs.
If you check my work history , you will be able have a clear idea about my betfair related experiences..
if needed , i can send you some demo versions of my past works for you to have an idea about how good im on this subject.
I'm waiting for hearing from you soon.
