ABOUT ME: Originally from the southwest of England, I'm currently embracing the digital nomad lifestyle, traveling between Thailand and Malaysia with my wife and two children. Before becoming an iOS developer, I worked as a chef, video editor, and computer repair technician. I started learning to program at age 30 (I'm 42 now) and quickly fell in love with it. My interests include classic rock, blues, dubstep, comedy, sci-fi, sunshine, and spending time with my family. I'm always striving to be better as a developer and a human.

"Chris was fantastic to work with. Very efficient, excellent communication and the solutions he put forward were top notch. A real professional and software development expert. He helped architect our prototype app and performed the very best practises throughout. He was highly familiar with all the Apple APIs we needed and understood the iOS eco system very well. I couldn't recommend him highly enough, he is a rare find. 5 out of 5 stars definitely."
