What others have said...

Carl has a fantastic work ethic, is quite capable, and finds creative ways to both solve and circumvent challenging iOS problems. We were lucky to partner with him at Hackerlist.
Mek Karpeles, CEO & Developer, Hackerlist Inc. (Custom Cut)
As the main front-end engineer for [our] iOS app, Carl performed an amazing job within a tight timeframe, translating product designs into elegant and well-organized code ... He has a good eye for detail when it comes to layout, color, and animation, which helps expedite communication with designers and improved the quality of the final UI.
Nikie Xiong, Product Designer, Bosch North America. (Navigator)
Carl regularly delivers incredibly solid code. [Our] iOS app is the most polished and best behaved app we have and that is entirely due to Carl's focus and attention to detail; you can't test quality into an application.
Matt Attaway, Director of Engineering, Digital Domain Inc.
Carl is a solid full stack developer and it's a pleasure to review his elegant coding style. Another strength is his ability to implement tricky UI features, coming up with creative and fun solutions.
Steffen Frost, iOS Developer, nearIM Inc.
Carl is a great iOS engineer and came through for us on a gaming project at the last minute, solving problems other engineers could not solve. He allowed us to finally take our app to market after other engineers kept it tied up for weeks with bugs. It was a pleasure to work with him. I recommend Carl to any company or individual seeking a talented, easy going iOS developer.
Leila Golchehreh, Managing Director, Lexplique LLC.
Carl is a pleasure to work with and he demonstrates timely responsiveness and technical competence. I would not hesitate to work with Carl again. He understood our needs and produced an innovative application in a timely manner within budget.
– Jon Eastlund, IT Manager, 511 Regional Rideshare Program.
