Hello,
let me start with my brief introduction, I have been working on odoo since version 4.2, it's been several years now. I have worked on each and every release from version 4.2 to v11, and now slowly starting a few projects on V12.
I have worked on a variety of projects involving customization implementation of different modules such as CRM, Sale, Purchase, Inventory, MRP, Project, HR etc.
Related to this project
I got the flow of JCC payment acquirer,
I have had worked payment acquirers module for odoo before, the acquirer I built before is odoo bitcoin payment and "mollie" payment acquirer.
I can do this very well, let's discuss.
regards
