When we had initiated our cap project, although specific instructions were clearly specified, however, many of the freelancers hadnât a clue on how to design this product.
Once we got a reply from Haradhan, we knew immediately he was our man for this project.
Haradhan is a superb freelancer, a good listener, aside from being very talented in his field. Pays attention to detailed instructions and implement them.
Wed are very pleased with this freelancer , as we will use him for other incoming projects.
