Dear wheatgenetics
I have been in this industry for 4 years and such jobs are my daily practice. This is my first time on this site and hence you can see that I do not have any ratings/testimonials to show you. I can assure you that if you work with me once, you will always work with me for these kind of projects.
I have experience on Google app engine,it is a cloud server. Using Android client i used to upload data to GAE data store using GAE api. I can use Amazon S3 Storage account to upload and retrieve data into Amazon simple DB, and i have good enough experience on developing Android UI.
