Before cooperating with IntexSoft, the client did not have a website for selling the product. That is why Koawach recruited IntexSoft specialists to create an adaptive e-commerce platform. A month before the release of the website, the client was invited to the famous German television show Die Höhle Der Löwen. It was expected that during the show, the number of orders will increase in tens of thousands of times. So they needed a platform, which can handle a sharp visitor boost and still work stable. After the ordering process is finished, each buyer had to get a confirmation letter. With so many orders in a very short period of time, there was a threat of emails blocking and the client's system could get blacklisted.



IntexSoft specialists worked on payment systems integration, delivery systems, and also created a unique custom backend part for the platform. The innovative system architecture of the website was specially developed and integrated into this project. For the end-users convenience, an adaptive version of the platform was developed as well, this allowed easy access to the website via mobile devices. The project involved third-party payment systems, protected by standard security protocols. Two-level security provided a secure protocol (HTTPS) between the browser and the server, and a secure protocol between the server and payment systems. At the data center, all servers are closed in the internal network, which is not accessible from the outside through the firewall (DMZ). Only the end user's requests pass through the first firewall. Access to the database, thanks to the second protection level, can only be done via one particular device by the certain protocol. In order to avoid blocking and blacklisting, in case of mass email distribution, the IntexSoft team, having tested various public servers, finally chose Gmail SMTP Server, where it was possible to set daily limits for letters auto sending. Control over the number and frequency of sending was carried out by the lining management system.

Methodology & Transparency

Since the client allocated a certain budget and set strict deadlines, work on the project was carried out according to the classical model of the Waterfall methodology. Although when delivering results to the client, the team followed the iterative approach. The IntexSoft team provided the client with access to the corporate project management system. Communication was carried out between project managers from IntexSoft’s and the client’s sides. They organized daily calls, where all the current issues on the project were discussed.
