## Beyond the traditional website

 

The web has evolved. Today, the browser is capable of running complex applications that previously required desktop installation.

 

At Avantit, we specialize in building rich, fast, and secure web applications. We use React and TypeScript for the frontend and .NET Core for the backend, ensuring a solid and maintainable foundation.

## Our Web Development Approach

 

### Single Page Applications (SPA)

 

Fast and reactive applications built with React and TypeScript that offer a fluid user experience.

 

### Progressive Web Apps (PWA)

 

The best of web and mobile: applications that work offline and can be installed on the device.

 

### Robust APIs

 

Scalable backends in .NET Core or Node.js, designed for high performance and security.

 

### Performance First

 

Extreme optimization to ensure minimal load times and better SEO rankings.
