What have
we done?

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.

By moving towards to open source programming language and tools, it is helpful in lowering the investment costs on the licenses such as the license on the Operating System and database engine.

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

Here is our portfolio.
