The technologies we work with — and one that almost no one still masters.
A direct entry point by technology name — for CTOs, tech leads and developers. Angular, React and Symfony for custom web applications, and Sencha ExtJS as a core competency for over 15 years.
Angular
We build complex, data-intensive business applications with Angular — from dashboards to process tools used by many people. Angular is especially well suited for applications that are maintained long-term and developed in parallel by multiple developers.
React
For applications where flexibility and a large ecosystem of libraries matter — for example when integrating AI features or building custom, interactive user interfaces.
Symfony
As a backend framework for data management, document generation and process logic, when a robust, well-maintainable architecture is required — often combined with an Angular or React frontend.
Sencha ExtJS — our core competency for over 15 years
As a certified Sencha Select Partner, we have supported companies for more than 15 years with the introduction, migration and further development of Ext JS applications.
Sencha Ext JS is a JavaScript framework for complex, data-intensive business applications with extensive user interfaces — typical for administrative software, internal tools and dashboards that stay in use for many years. That's exactly today's challenge: the applications run reliably, but the number of developers who still master the framework is shrinking. We're one of the few partners who both maintain existing applications and build entirely new ExtJS solutions.
Especially suited for companies with complex, long-lived business applications — such as administrative software, internal process tools or dashboards that need to run reliably for many years.
Code Reviews
Technical analysis of your existing application: code quality, architecture, performance, maintainability — with concrete, documented improvement recommendations.
Framework Updates
Version and security updates, without rebuilding the application from scratch.
New Development
When modernization makes more sense than further patchwork on an outdated codebase.
Training
From foundational training to expert workshops, so your own team can work independently on the application again.
