Hello,
I have a lot of experience with customisation and modules development for Odoo ERP (from v10 to v14).
I have successful experience of payment modules development (integration with payment aquirers) for Odoo. It was Amazon Pay payment acquirer and payment acquirers for local use in Ukraine, Georgi, Norway, and some special payment implementation like payment with cash or payment with C.O.D.
So I think I can help you.
If you are interested, feel free to contact with me to discuss details.
Thanks,
Max.
