About Me
Hi, I'm John! I started seriously programming back when I was in 6th grade, and I have worked with many different languages and platforms over the years. I started with C# but I have also spent a lot of time working with Kotlin, Java, Visual Basic, Swift, and JavaScript. I have used these programming skills to write apps for all sorts of platforms, old and new. These include Android, iOS, Windows, Wear OS, Palm OS, webOS, BlackBerry OS, and Windows Mobile!
My hobbies include programming, tinkering with computers, reading, writing blog posts, and spending time with my cats.
