Hey @lovall31
It is always recommended to hire someone who has past experience and has enough reviews to help you out and personally it doesn’t looks like that the person is trustable if they have not showed you any proof of their previous work or any past reviews so it is always recommended to be alert before granting someone access of your Shopify store.
If I managed to help you then, don’t forget to Like it and Mark it as Solution!
Best Regards,
