Hello World! I'm Justin Hopkins

I like to make cool stuff.

I am proficient in C#, Swift, Web Development and Design (PHP, HTML/CSS). I'm passionate about creating cool experiences with software design that bring together code with creativity.I strive to design apps and solve problems around the mantra that "simplicity is the ultimate form of sophistication."When brainstorming concepts for original apps, I like to challenge myself to find an interesting angle to expand (or reinterpret) existing solutions to problems - hopefully, in order to delight and surprise users._{In the 'featured' projects below, click 'Read More' for specific examples!}
