Bug Fixes for existing small Mac OS X desktop application.

I have an existing Mac application written in Objective-C that requires a small amount of bug fixing effort. The project is managed using a web-based bug tracking system (i.e. tickets) and Subversion is the source control system. This project is suitable for a Mac developer that is well-versed in Mac OS X desktop application development and is familiar with JSON, networking and application deployment. The majority of the fixes are UI/configuration related. Each bug that needs fixing will have a detailed description in its ticket. Each bug should be worked on independent of other bugs and source control checkins should be precisely controlled so each checkin only has code changes related to the ticket that is being worked on. Since the program is hardware related (microphone/speakers) it is best if you have real hardware not virtual machines. The program can run on x86 OS X 10.6.x and also x64 with the newer Mac OS X versions. There is some platform specific code that enables some platform-specific features. Bug fixes will need to be verified on both 10.6.x x86 and newer OS X versions so you will need to have those platforms available to test the bug fixes. This program also has a Microsoft Windows counterpart so it would be useful if you had a Windows computer or VM available to run so you could test the Mac application interacting with the Windows version. I require that code be well commented and should be easy to read and understand. The fix should be documented in the bug tracking system indicating how the problem was approached, any failed approaches, what the fix entailed and any caveats related to the fix. A complete description of what testing was performed should also be recorded in the ticket's comments. Before checkin the code should be emailed as a patch for a pre-checkin code review. Once approved, the change can be checked in. If you would like to apply for this job, please reply with detailed information on: a) Your qualifications for this job (sample code would be great) b) A description of the Mac OS X hardware you will have available during the job c) A description of your availability to work on this project (# of hours per week) Applications that do not include the above information will not be accepted or acknowledged.
