Modernize existing software
I support the porting, refactoring, and step-by-step modernization of existing Windows and business software — without unnecessary full rebuilds.
Modernize and reliably evolve existing Windows and business software
I help companies stabilize, modernize, and further develop business-critical software — using C#/.NET, C++/MFC, SQL, Windows Services, interfaces, and device integration.
Whether it’s a long-established desktop application, a complex interface landscape, or a legacy system that has become difficult to maintain: I work my way into existing solutions and further develop them pragmatically.

Initial check and rough assessment possible
- Take over existing software safely
Analysis, bug fixing, refactoring, and reliable further development of long-established systems - Modernize in a maintainable and pragmatic way
Step-by-step improvement instead of a risky full rebuild - Reliable in live operation
Stable further development of desktop applications, Windows Services, interfaces, and device integrations
How can I help?
Integrate interfaces and services reliably
I develop and stabilize APIs, data flows, Windows Services, and device integrations so that systems communicate reliably and processes run smoothly in the background.
Take over and further develop business-critical systems
When know-how is missing or software has become difficult to maintain, I take over the analysis, stabilization, and pragmatic further development of existing applications.
Typical situations
- The existing software is still running, but technically outdated
- No one on the team really knows the system anymore
- Interfaces have grown over time and have become error-prone
- A complete rebuild would be too risky or too expensive
- You need an experienced developer for a grown, existing system
