A computer-based system to integrate code changes for a software application is provided. The system detects when a requested code change for a branch of the software application conflicts with another code change, and generates a blocked change notification corresponding to the detected conflict. The blocked change notification includes a blocked change identifier corresponding to the requested code change. The notification is delivered to a user device, which responds with a conflict resolution response that includes at least one code change file associated with the requested code change, along with an integration annotation that conveys the blocked change identifier and a branch name identifier that identifies the branch of the software application. The system acts upon the integration annotation to integrate the at least one code change file into the branch of the software application.
