Jeremy DELREY CTO at A-Pharm

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 decided to develop a mobile application for our customers.Firstly we Googled different companies and then after the communicating with 7 different companies, we decided to work with sst. The main request from our company was to create the best user interface and functionality. Results came immediately, I am as a head of client support saw results more than other departments. Thousand positive feedback from the customers regarding the application and how it works.

Web Development Review from Victor R
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.

Chandan R Jadhav's Review Sourced from Google
I had some efficiency issues in my firm from a while, came across them on linkedin and reached out just to give a shot. Things clicked, they audited my business and just in few months they helped me automate a lot of essentials. Visibly i can see the impact which i haven't from few years in my business. 10/10 recommended if you want to simplify/improve/automate your processes.
