I have been a software developer for more than 30 years. I'm familiar with C, C++, C-Sharp, Objective-C, Swift, Java, Javascript, Python, PHP, SQL, MySQL, iOS, Android, Xamarin, CSS, HTML, Xcode, Visual Studio.
I focus on writing clean, modular code whenever possible. I realize that I may not be the only developer working on any given project throughout it's lifetime, so I make it a point to make sure the next developer can easily pick up on what I have done.
