  7. Jon Mandell

    Passionate iPhone Developer

    United States - Tests: 1

    I have done a variety of iPhone Apps, but the more significant ones I've done have involved displaying content from websites and webservices. This includes authentication with server, storing passwords in the iPhone keychain, or just scraping websites. I can use SOAP or REST or other formats for HTML data communication, whichever your organization uses. I've also used JSON data structure. I convert all these formats to iPhone Objective-C Data (using plists to Core Data), for displaying your data in the wonderful iPhone user interface features that iPhone users come to expect. So far these have been for a few large companies that have their own app store for their employees. A little about me. After years of developing control systems programs for industries I decided to retire from my "day job" and really do something I'm passionate about ... which is programming applications for the amazing iPhone. Since I'm retired, my second career can be for the enjoyment more than the money. Therefore I can provide very cost effective iPhone applications for you to provide to your customers. http://www.mandellmobileapps.com
