One of the linchpins of Digital Transformation was and continues to be the Web - regardless of whether companies are looking to interact with customers, with employees, or with new digital elements, such as in the 'Internet of Things'.

Provided that they are flexibly adaptable, expandable and scalable, Web solutions support all kinds of digital scenarios over a long lifecycle. We develop lasting, user-centric Web platforms and portals, implement the Applications, preferably with open-source technologies, and integrate the solutions into our customers' IT landscapes.

As Web Applications nowadays are accessed via a huge number of different devices, the user interfaces must automatically adjust to the various usage situations. Responsive user interfaces are therefore an indispensable component of our integrated web solutions. Wherever possible, our web application experts rely on progressive Web Apps to bring the user experience even closer to the capabilities of native Apps.

Technology Stacks


  • React, Angular, Vue.js, StencilJS, Express.js, Ruby on Rails, Sinatra
  • TypeScript / Flow, JavaScript (ES2017+), Ruby, Elixir, Less/Sass
  • Webpack, Yarn
  • Styled Components, ImmutableJS, LernaJS, Redux, Mongoid, DataMapper, GraphQL, REST, Backend for Frontend, SPA

Mobile Web

  • We create our apps for mobile devices using web technologies as well as Android and iOS. Here, depending on the use case, we rely on React Native, for example. Compared with the hybrid apps that were often used in the past, genuine native apps can be created in this way. In terms of appearance and responsiveness, it is no longer possible to tell these apps apart from those created using Java or Swift. Incidentally, there is no longer a need to use two separate projects to develop React Native apps, as the code basis can be used for both platforms in the vast majority of cases.

  • Spring Data, JPA und Hibernate, STOMP, JAX-RS (REST), Web Container (Tomcat, Jetty)


  • PostgreSQL, MySQL/MariaDB, Oracle, MS SQL Server, MongoDB, Redis, Cassandra, Memcache, Liquibase


  • Elasticsearch: The search machine is based on Apache Lucence and can be easily addressed by means of REST interface, searching through vast quantities of data in ultra-quick time.
