      eCommerce Development Review from Jeremy DELREY

      We decided to create an Online shop for selling medicines. So we started with negotiations of the concept and the collection of the requirements. Then team provided us with the technical description of the store and a few mockups of it. After approving everything they start creating a solution. I think that we're about 10-12 people in the team who worked with us. We launched shop and receiving profit from it, I think that's the best outcome.

      We had a problem with a tremendous corporate website, which was very bad and not working. So we decided to create a new corporate website. I have asked a few marketing specialists to give us a contract of good It companies, also find good reviews about SST. As a result, we finally have a fantastic, well-designed, and working website. Also, the traffic of new customers increased by 200%. Also, SST has a suitable methodology for providing the project results in real-time.
