Hi,
I am an experienced C# and Javascript developer.
I can do this for C# and Javascript with no problem. I will of course fully comment the code.
But I won't do Ruby or PHP.
If you need to have only one developer for this project, I will have to do some researchs on those programing languages before giving you the code samples. Count one or two days more for this and add 50 USD to the current offer.
Please, let me know your choice if you think I'm a valid candidate.
Regards,
Olivier
