Hello,
Honestly, I don't have experience with Hybris e-commerce platform.
I just went to their web site, it's a platform based on JEE.
Then I'm not worried, since I'm an experienced Java/J2EE web application developer.
I'm pretty sure I can catch up the architecture very quickly.
I'm willing to take half hourly price for the first month.
Please check my profile, see how other project owners said about my service.
Contact me if you are interested.
Thanks,
Rick
