Sam is a developer, an author and a trainer, working for Razeware, the company behind the curtain at raywenderlich.com. Despite starting out in academia working on computer vision problems, he's spent the last 5 years working in the mobile world, primarily focused on making delightful things in iOS. Whilst he's probably wrangling with some kind of code, recording videos or presenting talks during the day time, you'll often find him out entertaining the masses by night, armed with his trombone and killer dance moves. You should say hi to him. He's nice. Honest.
