Our Know How

With ArtButler, we were able to strategically apply our strengths in modernizing complex legacy systems, cross-platform development and implementing modern SaaS architectures. The result: a powerful, future-proof solution for digital art management.

Legacy Modernization with Modern Architecture

We transform established desktop applications into future-proof web and mobile solutions. Through clean refactoring and clear architectural decisions, we create the foundation for long-term maintainability and scalability
Cross-Platform Development with a Single Codebase

Thanks to modern frameworks such as Angular, Ionic and Capacitor, we develop applications that run equally performant on web, iOS and Android – with consistent user experience and minimal maintenance effort.
Offline Capability & High-Performance Synchronization

We implement offline-first architectures with local cache and differential data synchronization. This ensures applications remain usable even without internet access – while maintaining high performance and data security.
Cloud-Native Architecture for Maximum Flexibility

We develop cloud-native software solutions that scale dynamically, provide high availability and integrate seamlessly into existing infrastructures. Updates are deployed without downtime – ideal for continuous productive operation.
UI/UX Redesign for Maximum Usability

We design modern, touch-optimized user interfaces that map complex processes intuitively. Through iterative testing and user feedback, we create an experience that combines design, function and efficiency.
Agile Development with High Implementation Speed

Through clear communication, close coordination with the product owner and flexible sprints, we were able to develop a market-ready product in a short time – live and scalable for future requirements.
