Hi,
I have been in this industry for 6 years and such jobs are my daily practice. I am very new on this site and hence you can see that I do not have much ratings/testimonials to show you, and whatever few feedback I have, are very promising and positive. I can assure you that if you work with me once, you will always work with me for these kind of projects.
I have also experience in Software Product management,solution building and software development using Open Source Technologies in both Mobile (RhoMobile, PhoneGap) and Web (Ruby On Rails). As I have worked on both mobile and web technology, I have good experience of creating API from web application for mobile.
I am a Microsoft HTML5,CSS3 and jQuery certified developer having good knowledge of version Control( GitHub, SVN ) , Deploying RoR application on cloud(Amazon-AWS S3 EBS, Heroku), Social media API integration(Facebook, Twitter, etc)
I have already worked on E-commerce websites, one SAAS product based on Supply Chain Management, customized search engine, appointment system, third party integration.
Thank You
