Briefly, let me provide a little background information about myself. I'm a freelance developer who holds a M.S. in Software Engineering from Mercer University and have spent the last 15+ years developing software and working with a variety of technologies and programming languages. As a software engineer I have developed code for several operating systems (Windows, Linux/embedded Linux, Mac, iOS and Android) and I am comfortable writing desktop, mobile, or web code. I have worked on a variety of different iOS/Android apps over the years and am quite versed in developing iOS/Androids apps with both swift and obj-c as well using both Java and Kotlin to create apps. Over the years I've worked on many apps ranging from large to small as well as both enterprise and apps released to iTunes/play store. As such, I’m up to date with the latest iOS/Android coding standards and already have the tools in place to do development and could hit the ground running.…Briefly, let me provide a little background information about myself.
