Nawjesh is a pro in WordPress. Delivered exactly what was required for the project. It was a custom advanced calculator with special requirement development with WordPress for subscribed and logged in users and it worked like a charm in the end. The generated PDF was spot on. Will definitely work with for my future works.

This seller worked very quickly to finish a project that other coders could not do. He stayed up very late to help and finished the project very early and did a great job. I recommend using this coder if you need any PHP or Wordpress help. Thank you very much, from one happy customer.
