Joint team development with IRIS?

I'm wondering if there is no way to do joint development on one IRIS project. Is there a way to work with 3+ team members on an IRIS application using git and version control?

So far we have to use im/export which blocks parallel development and sometimes we loose data mappings on the way.

Are there any best practices?

Thanks in advance!
