What challenges faced the team

The client came to us with an already ready and successful application, as well as ideas for improving the quality of communication and user experience. Therefore, as part of the work on the project, we had to correct the existing problems in the software and introduce new features that would make Comexcel even more successful on the market. The solution of these tasks was handled by an individually formed team of three specialists.
