  • Hey Frank,

    My name is Chris and I’m the software engineer behind the iPad app ‘Drawing Pad’. Its a fairly popular app in the iOS app store called Drawing Pad, see here:

    I’m having some small, strange OpenGL ES2 issues that I’m looking for help on debugging. I’m the only programmer and sometimes after looking at code for months it is hard to find where I’m going wrong. As Linus’ law says, many eyeballs make all bugs shallow… hopefully having someone else who is good at OpenGL can look at it and help me out.

    …This is also my first published app with OpenGL by the way. 🙂 When the iPad 3 came out in 2012 I realized that the only way to get retina performance with on-screen drawing was to use OpenGL. I think I did pretty good all things considered.

    Feel free to email me or you can contact me on skype (clott01) or google chat ( if this is something you are interested in and are willing to help out. We’re willing to pay a couple hundred dollars per hour for consulting if you think you could squash it..
