Hi Alex,

Yes, it is.
Alex wrote:Is it good practice to have developers with different specialisms working on a Joomla site at all?
I'm assuming this is non-github related...Yes, just as long as someone is able to oversee everyone's work and direct people appropriately, otherwise it can get messy. Either way, proper access control needs to be set for everyone and that makes life much easier in the long run.

Yes, in regards to code, however if you're not able to work with it, then it's of little use. It can be hard to learn to be honest.
Hope this helps! :)
Kind regards,
Nick
