Your agency for professional web development

Successful web development always starts with a customised strategy that is perfectly tailored to the needs of the company.

Our range of services includes the development of various web applications, from single page applications to smaller tools and complex web applications.


The languages we speak

Every application is individual and unique. That’s why our app developers discuss which technologies we will use with you before each project.

Web applications such as online platforms can be developed using Angular, for example. Mobile apps, on the other hand, are programmed with Flutter. These must be aligned with the respective operating system (i.e. Android or iOS). We identify which technology is best suited to your project.


We will guide you through the process

// how we work

Our development methods

Our software agency focuses on personalised strategies to achieve excellent results:

Scrum approach – and Kanban methods
Agile development methods such as Scrum and Kanban let us react quickly to changing requirements and continually optimise product development.
Continuous Integration / Continuous Deployment (CI/CD)
The use of CI/CD pipelines makes the automated provision of software easier, speeding up the market launch of new functions and ensuring continuous quality control.
Design Thinking
Design thinking places the needs and perspectives of users at the centre of product development and enables the creation of intuitive and user-friendly products.
Lean Development
Lean development principles aim to reduce waste and maximise value flow, allowing companies to work more effectively and concentrate on developing features that provide real value to customers.
Domain Driven Design (DDD)
DDD focuses on modelling software around the core functionalities and business areas (domains) and uses the concept of "domain story telling" to communicate and develop requirements and connections within the domains.
Service oriented architecture (SoA)
Modern IT companies rely on SoA to split software into independent services, which promotes scalability, maintainability and flexibility.
Collaborative culture
A collaborative culture encourages cooperation between development and other areas to guarantee effective and efficient product development.
Security and compliance
The security of software and data is a top priority, so modern IT companies integrate security and compliance checks into the development process right from the start.

How do we develop web applications?

As a professional web development agency, we always endeavour to implement your requirements and wishes in the best possible way. That’s why we work with you to develop these in an interactive workshop. It is important which features the web application should have, what makes it unique and which customer problem it solves. During the actual web development, we use all common technologies and programming languages. We always look at which frameworks, languages and databases are the right ones for your project. Even after the web application has been developed, we are available for updates, improvements and changes in order to offer you good long-term support.
