Worked on the odoo/upgrade-util repository to enhance migration reliability and customization support in Odoo environments. Developed a safeguard in Python for the move_model utility, ensuring that email templates are only updated when the relevant model column exists, which preserved user-created templates during version upgrades. Additionally, implemented Smart Foreign Key Type Inference in the create_column function, allowing automatic detection of foreign key types and reducing errors from hardcoded definitions. Focused on backend development, database management, and unit testing, these contributions improved both the stability of upgrade processes and developer productivity by minimizing manual intervention and preventing unintended data overwrites.
