Hello, my name is João Chagas and I'm from Brazil.
I have experience searching for products for resale in FBA or FBM on Amazon. I've worked with all the apps listed by you and I believe it can be of great value.
I have an average of 10 to 20 products per day, all of which are serviceable. I can also help you in the area of customer service and other functions that a seller has on Amazon.
I have experience with OAGenius, for more practical and quick listings.
I have advanced computer skills, I used to work with programming, I won't have any problems if I need to learn to use new programs or tools.
My English is advanced, you will have no problems with that.
I appreciate the opportunity and await your contact.
