We have involved in many customized software solutions since 1998 (under "Evotech System Enterprise"). In earlier days, we were using VB6 (Visual Basic). Later in year 2008, we were switching to C#. Since 2024, we have started using Node.js + PostgreSQL for all new projects.

What matters a successful solution is on both the development costs and the implementation costs.
