I am an IOS developer by profession with two years of experience. During this tenure I developed 5 applications. One for a Business corporate named 'XIQ' and three others for Medical field and client with clinic named 'MI Express Care'. Fifth one was created for a Sales person.
All of these applications contain rich use of UI Elements and other APIs like live video, chat, google maps, push notifications, google+, facebook, linkedin and twitter integration etc.
I also have command on Auto Layouts i.e. designing for multiple size screens of ipad and iphone.
I can look into your project and apply my experience for adjusting constraints for iPhone 4 as I have had been developing all of my applications for all types of screens and devices .
I am quite willing to do your job.
