TypeScript was designed for complex applications. The strict type system makes it easier for us to develop according to the clean code principle and enables translation into valid JavaScript code that can then be executed in the browser or on the server.

For server-side programming, we use PHP, a scripting language that has been established for decades. No matter whether it is about the creation of backend applications or command line tools, the wide range of system libraries makes it possible to develop the right backend for every imaginable use.

The popular open source tool provides us with a portable and consistent runtime environment that is used by us in development, continuous integration and also in production. The containers with the isolated environments are ideal for logical and physical separation of application components, thus providing an ideal ecosystem in terms of system security as well.

Using the OpenAPI standard, we define our RESTful APIs. The API comes first for us, which is the working foundation for frontend and backend application. We love interfaces designed according to the JSON:API or JSON-LD specification.

We use Symfony along with API Platform to create fully testable applications for server-side execution. Using these frameworks, we bridge the gap between data persistence layer and front-end application.

On the frontend, we use Angular as a framework to create state-of-the-art web applications. Here we pay great attention to unit and interface testing.

Astro is the web framework for content-oriented websites that impresses us above all with its speed and features such as SSR (Server Side Rendering) and Static Site Generation (SSG). This is one of the ways we ensure that we create optimal conditions for search engine findability.

React is the second major frontend framework we use. We build many of our components with React and use it along with other web components to build web applications.

Directus is an open source platform that functions as a Headless CMS and Backend-as-a-Service (BaaS). It enables the simple management of content and data in SQL databases via an intuitive user interface. In addition to the versatile application options, we particularly appreciate the continuous further development and the strong community.

We are cloud natives. This means that we provide our scalable applications on cloud infrastructures. To achieve this, we use Kubernetes. Using the standardized tools, Terraform and Helm, we manage containerized workloads and services on this extensible open source platform.

We use Terraform to manifest the infrastructure of our projects in the source code. This allows us to easily keep it up to date and apply it to different environments. We also maintain our own Terraform modules to transport recurring parts of the infrastructure from project to project.

We use Ansible as an automation engine for provisioning, configuring and deploying our applications. To minimize manual processes, we keep the infrastructure as source code. This allows us to extend, duplicate and update it without much effort.

Git is the standard for version control. We use platforms like GitHub and GitLab to version source code, perform code reviews, and automate related processes. Processes for testing, build, and deployment are part of every project.
