GitHub Commit History Adjustment

Hi there, i have a kind of unusual task, I have some history on GitHub for the last 4 years but my last year is empty with no commits as I was working in the closed repository. Is there any way how you can help me to add a QA /Java automation project to the last year with past commits or merge other GitHub account with mine with real commits which made last year to make my last year commit history look busy? It must be a JAVA/Selenium/TestNG/QA automation project.
