    David did the requested job perfectly. He originally even over-delivered by providing an additional optimization I didn't ask for. It worked great in the sample app I provided him for the job. Unfortunately, the extra optimization broke our real app after we copied the code from the sample app. But David responded fast, diagnosed the issue and disabled the extra optimization.

    Project Description:Following up with the last project, I need my existing code to avoid allocating too much memory when extracting video from a ZIP archive, so that the app does not crash due to insufficient memory.

    Hey David,We spoke months ago about working together to build Fostr - an iphone app that let&quot;s people share the creative projects they&quot;ve always wanted to finish. I had to sort a bunch of things out and I cut out a bunch of features of the app so I can launch a solid app...I have prepared a PDF that shows the app screen in detail and points out logic and features. you wouldn&quot;t mind, please take a look at the PDF and let me know if you are interested in working with me on this. More than anything, I really want this app to be solid. We will need to add features down the road, I just need a strong foundation. As you know, setting up the proper database and an API to tie into the backend as so important... We would use a PHP/MySQL in the backend...I am looking forward to hearing from you, if you are interested, and if you have examples of recent ios apps you&quot;ve built... and, with your current workload - how long you think something like this would take...Thanks David!Sean
