Web app for Koawach - IntexSoft

Web app for Koawach

A large-scale web application for selling hot drinks made of cacao and guarana.


Initially, Koawach co-founders hired our team to create a responsive eCommerce website. A month before the release, the clients were invited to the famous German TV show “Die Höhle Der Löwen. They expected an enormous increase in visitors and orders. So the real challenge was to develop a web application, which could keep up with a sharp traffic boost.

IntexSoft specialists worked on payment systems integration, logistic systems integration, and also created a unique custom backend part for the platform.


The dev team developed the innovative system architecture and integrated it into the project.For proper usability, we also developed the responsive version of the platform. This allows easy access to the website via mobile devices.


Speaking of the ordering process, each buyer gets a confirmation letter after the order is done. Considering an expected great boost in visitors and, in particular, buyers, there was a threat of email spam blocking and the client’s system could get blacklisted. In order to avoid blocking and blacklisting, in the case of mass email distribution, our team tested various public servers and 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.


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 a certain protocol.

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 the intermediate results to the client, the team followed the iterative approach.


The IntexSoft team provided the client with access to the project management system. Koawach was also provided with a testing system, where they checked the platform operation. Communication was carried out between project managers from IntexSoft and the client’s side. They organized daily calls, where all the current issues on the project were discussed.
