    I am looking for a very professional IOS developer to create an app like Instagram where users can share images and videos (10 secs max) with other users who can share, comment, and like the photos or videos shared. The app will also allow messaging among users. The developer will also build the server side of the app as well. It is very important that the person for the job is very skilled in IOS 7 as IOS 7 specific features will apply to the app. The app will be strictly storyboarded, and have a responsive UI. I also want someone that is very detailed in what they do. Developers who just know how to code and don&quot;t know how to apply the details of the elements of the app effectively will not be a good match. In other words, I don&quot;t just want a someone who can code, I want someone who can create. Interested applicants should please not bother telling me how many years you&quot;ve been doing IOS development or mobile apps. Let your samples speak for you. Send me samples of apps you have developed that are on the app store.

    We are looking for a professional mobile app builder. This may very well be a complicated app to build so we are looking for someone that is serious and tired of building less than great apps and would like to challenge themselves to create an extremely successful app. We require a person that lives day by day building apps, and knows everything there is to know about Objective C and its capabilities. All coding must be done properly without bugs, or flaws. For someone that builds apps consistently, this may be something you can do quite quickly but we are only interested in someone that can do it right, work efficiently and give us the sole copyright privilege for being the designing engineer and owner of the app. If you feel you are qualified for this, please respond with a message and please explain in some detail how you are qualified for this project? We would also like to see some &quot;proof&quot; of the work you have done and it must be credible and verifiable work. Please only respond if building Apps is your specialty and you have built something worth bragging about, and/or are ready and capable of doing so... We are starting this project and want to hear from professionals that can get this launched soon and give us a salable APP hardcopy for the starting project price of $200-$300. If you can build what we need built, we will all financially benefit very well from this project. Thank you :)
