Ruby, Ruby on Rails developer needed for making some changes in GitLab API source code

This is a quick job that should not take a lot of time for a Ruby developer. We need a small change in the GitLab API. Details of the work- Git Graph needs the references a commit is pushed to (check refs in this: [login to view URL]). And GitLab open-source code is ready API ([login to view URL]) that doesn't give us all the references, in which branch this commit pushed to, of all the commits of a repo in a single request. Right now we have to make a request for each commit in a repo, to fetch the references of that commit, but in that refs, we are getting all created branches in each commit ([login to view URL]). We want to change the way GitLab API does this by modifying the API code to GET all the commits and their references (of the branch in which the commit pushed to) of a repo in a single API call. Please do not apply without reading the full post. If you are interested, please apply with 'Have read your GitLab API post'. We will decide a cost and then will pay out once the job is complete.
