I want to express my gratitude to SimbirSoft, which collaborated with us for developing one of the largest recent Russian IT projects to create an information system to manage housing and communal services. For two years we worked with a dedicated testing team from your company, whose specialists took an active part in the system's testing, implementation and further support. The created resource will play a huge role in the development of the housing and communal services of the country, uniting citizens, authorities and various organizations in a single information space, facilitating their interaction. Thanks to the SimbirSoft testing team participation in the project, it was delivered on time. Separately, I would like to note the lead tester Y.Padyanova, who not only selflessly participated in the task verification, but also engaged in the formation and optimization of processes on the project, led the team and trained newcomers. SimbirSoft employees perfectly coped with their part of the work. We are pleased with both your company's contribution to the project’s success and the human relationships that have developed between our companies during our collaboration.
