Worked on the ovh/terraform-provider-ovh repository to enhance the reliability and correctness of firewall provisioning. Focused on a targeted bug fix that addressed an issue where the 'enabled' field was incorrectly sent during firewall creation, which previously led to provisioning errors. By ensuring this field is only included during updates, the change improved idempotency and reduced deployment failures, aligning the provider’s behavior with API expectations. Utilized Go and the Terraform Plugin SDK to implement a low-risk, maintainable solution. The work demonstrated careful attention to API semantics and contributed to a more stable user experience for infrastructure provisioning workflows.
