+# Frui.ts business overview
+
+Nowadays, front-end applications are no longer just static websites with some JavaScript scripts used for simple validation or content animations - they are complex and business-critical applications that happened to run in a browser window. Therefore, front-end development requires the same effort in software architecture and quality control as any other part of the software solution.
+
+We have built Frui.ts to bring development standards of backend or desktop applications to the dynamic field of HTML front-ends.
+
+Frui.ts follows clean software architecture recommendations with a strong separation of concerns. Thus, the front-end application itself consists of multiple layers with clear responsibilities such as presentation layer, business logic layer, or data access layer. With that built-in the app from the beginning, our solutions are ready for long-term development and maintenance with no compromise of costs, initial setup, or development speed.
+
+The presentation layer follows the Model-View-ViewModel pattern, which enables a clear distinction between the data and its actual visual representation. Two-way binding makes forms input, validation, and other data-related workflows implementation straightforward.
+
+Our applications' inner structure follows the high-cohesion, loose coupling principle with dependency injection and message bus at its core.
+
+The code is written in TypeScript, a modern, Microsoft-backed programming language with static typing, compile-time checks, and robust development tooling.
+
+**Ultimate goals**
+ - Short- as well as long-term costs saving
+ - Adaptability to business needs and changes
+
+**Core principles**
+ - mature application architecture
+ - separation of concerns
+ - inversion of control
+
+**Core technologies**
+ - Typescript
+ - MVVM
+ - MobX
+ - React
+
+**Benefits**
+ - Reliability
+ - Maintainability
+ - Extensibility
