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.
