Opera Software, improving the
Macintosh interface for the company's
Opera browser. In February 2010 he wrote in a blog post that after working on a long-term project he wanted to do something different. For that reason he stopped working full-time at Opera and does freelance work again. According to an interview with Kate Musgrove from the
Affinity Spotlight, Hicks said his favorite design done at the time was working on the Spotify icon in 2014. This project combined his love of design with his love of music.

In July 2016, Hicks announced on his blog that he's finishing working for Opera from August 2016 and is "back in stock". ==Personal life==
