quality test on streaming site
Surinder helped me set up a site and the i nteraction with him if very professional. Many freelancers have weak business manners but not Surinder. He pays attention to detail, he knows how to communicate and does it well. He is a fine collaborator and is very cooperative. He used React and NestJS very effectively and the result is above my expectations. Give this man your work, it will turn out fine.
