I wish to apply for a master's in CS in the United States as an international student. It has been quite some time since I graduated and I currently work as a software developer.
While I have worked on several projects in work, would it be necessary for it to be verified through a professional letter of recommendation (LOR)? I am unable to get a professional LOR from my current employer but I can get it from my past employers. Further, would it be necessary to share a link to my Github repository in my academic resume? I don't have a strong Github profile right now.
