I'm a software developer with 3.5+ years of commercial experience, specializing in Odoo ERP customization and backend development. Over the past 2.5+ years, I've been working extensively with Odoo Community and Enterprise editions across versions 16 through 19, helping businesses tailor their ERP systems to match real-world business processes.
My experience is primarily focused on customizing and extending standard Odoo modules, while also developing custom modules from scratch when required. I've worked with Sales, Purchase, Inventory, Accounting, Rental, CRM, Website, Project, Helpdesk, Subscription, Manufacturing, and other core applications, implementing business logic, workflow automation, security rules, QWeb reports, email templates, controllers, scheduled actions, and user interface customizations.
I've also participated in module migration projects, adapting custom modules between Odoo versions (including Odoo 16 to Odoo 18), and have experience deploying and maintaining Odoo environments using Docker and Odoo.sh. In addition, I've integrated third-party services such as PayPal, including working with the PayPal Sandbox environment for development and testing.
Before specializing in Odoo, I spent a year developing enterprise applications with ASP.NET Core and Angular, giving me a solid understanding of full-stack application architecture and modern software development practices.
What I bring to a project:
1. 3.5+ years of commercial software development experience, including 2.5+ years focused on Odoo.
2. Strong experience with Odoo 16–19 (Community & Enterprise).
3. Custom module development and extensive customization of standard Odoo applications.
4. Python, PostgreSQL, XML/QWeb, Docker, Git, Linux, and PyCharm as part of my daily workflow.
5. Experience with workflow automation, reports, security, controllers, basic OWL/JavaScript customization, and third-party integrations.
6. Deployment experience with Docker and Odoo.sh.
7. Bachelor's degree in Computer Science from NTU "KhPI", with additional training in automated testing through EPAM.
8. Clear written English (B1) and experience working in Agile development teams using Git and collaborative workflows.
Programming has been my passion for over 10 years, and I enjoy building clean, maintainable solutions that solve real business problems. Whether you need to customize an existing Odoo implementation, develop a new feature, migrate modules to a newer version, or integrate external services, I'd be happy to discuss your project and help find the right solution.
