I'm an Odoo Engineer with over 7+ years of experience implementing and customizing ERP solutions, with a passion for Business Process Automation. In my Odoo journey, I’ve had the privilege of working on diverse projects for clients worldwide, enhancing their business operations through tailored Odoo ERP solutions. Here’s a snapshot of my experience: Swiss Project: I spearheaded the migration from SAP to Odoo ERP, developing custom modules for Swiss QR code e-billing, multi-country tax calculations, and procurement/order management. I also built a corporate website and APIs for integration with their proprietary payroll system. US Project: I crafted a custom unified view for various modules, developed a backend theme, and integrated the system with a mobile app. Australian Project: I developed custom APIs and a mobile app for a client in the construction & audit industry. Belgian Project: I managed a services project involving theme development, custom module development, and handling Odoo related tasks/tickets/bugs. In addition to these, I’ve enhanced the community Odoo version with custom features for a Swiss-based ERP/CRM and IT service provider. These enhancements include payment reconciliation functionality, invoice generation with barcode payment information for Swiss companies, Azure AD integration including Microsoft SSO, proprietary HRMS integration, SharePoint integration for project file management, and Stripe payment integration. I’ve also worked on various other Odoo customization projects, including the Payroll Reports Module from Odoo v10 to v14, the Payroll module from v11.0 to v14.0, a Transaction module for a Real estate business from v15.0 to v16.0, and an Accounting module from v15.0 to v16.0. My clients for development and maintenance work in Odoo include 2bit , wift, and powagroup. I’ve successfully customized Odoo apps to meet the specific needs of my clients across different industries, including construction, retail, and manufacturing. I provide ongoing Odoo maintenance and support, and perform customization and feature enhancements in their Odoo ERP system to meet their business requirements. My team is involved in Odoo standard unit testing to ensure error-free working of their Odoo ERP system. I have migrated Odoo modules from older versions to the latest version i.e. Odoo 14 and also enhanced its features according to the client’s requirements. This extensive experience with Odoo ERP implementation and customization makes me a valuable asset in any Odoo-related project. I am always happy to discuss requirements in more detail and provide tailored solutions that meet specific needs. I look forward to hearing from potential clients and partners. Best Regards. Megha
