Wix: multilingual product pages using Content Manager (now it's all one language)

Hello! I'm working on a simple product page in Wix, where products are read from my Content Manager database. It turns out that there is only one database for each language, so english version of website downloads data from the polish database, so it's still in polish. Full multilanguage solution requires additional programming. I'm looking for a developer who'll help me in creating such solution.
