Specialists in modern web development
We develop custom web-based applications, complex websites, and bespoke software solutions. Our projects are implemented according to modern web standards, optimized for usability, accessibility, scalability, and performance, as well as in compliance with the GDPR and best practices for security, including the IT Baseline Protection guidelines.
Our clients include medium-sized businesses, such as those in the construction industry, event sector, or media companies, as well as public sector clients.


Technical Expertise & Commitment to Quality
We use hexagonal software architectures, support PSR standards for improved interoperability, and develop in local environments using Docker. For continuous quality assurance, we utilize static code analysis tools, code reviews, and testing in automated pipelines.
On the server side, we work with modern PHP 8.x (strict typing, OOP), for example using the Slim or Symfony framework. On the client side, we use TypeScript/JavaScript, for example with Vue.js and SASS. We are experts in the intuitive open-source content management system MODX and actively contribute to its development. Additionally, we work with the file-based CMS Kirby.
Agile Project Management & Partnership
We rely on agile methodologies such as SCRUM to implement projects in a structured way and assign each project a dedicated project manager and technical contact. Our collaboration is efficient, transparent, and on equal footing – ensuring long-term project success and lasting client relationships.
