I have worked in Odoo for past 7 years. There are several modules and functionality I have developed while I was in the company at India branch. I have worked in customizing accounting reports for Thailand based client. Few more customizing work for German client. Sale, Purchase, HR, Account, Project and CRM modules in which I've worked the most. Functionality and technicality both I've known better. Apart from addons modules I also pursue knowledge about odoo framework thoroughly from V5 to V8.
