If you are looking for a twitter application developer, you're in a right place. I have experience in creating many twitter application. I can't provide all of the links because of the NDA, but I am providing two of the project links:- 1. File sharing application with twitter: Task was to build a file sharing application with twitter. Preview is enabled for image(with watermasing the site name), mp3s or video. Authentication is done via twitter oauth (sign in with twitter). There is other misc. featues also. As per NDA I can't give you the exact url, but you can see the project description on:- https://www.getafreelancer.com/projects/PHP-Website-Design/Twitter-App-Developement.html Status: Completed Review: You can get the review on my getafreelancer profile(https://www.getafreelancer.com/users/feedback_574314.html). However I am quoting it 2. Automated twitter background changer: Task was to create a automated twitter background changer script. Also user will automatically follow the owner of the site and post a tweet on his own profile. Authentication is done here by curl. This one is also a gaf project(https://www.getafreelancer.com/projects/Script-Installation-Twitter/Twitter-API.html). The site is already created. I just integrate twitter api to automatic apply the twitter background functionality. You can preview it live on FreeTweetGraphics.com - Free Twitter Backgrounds - Free Twitter Graphics =>click on "install this background" -> give your twitter username and password => after that you are done. I am experienced in creating web apps using php and java struts. I have created some other twitter application mostly for some resellers with strict nda. If you want to more about my profile just pm me. Regards BizTiger
