Stabilize business software, digitize processes, and reliably further develop existing systems

I support companies in keeping their existing software stable, reducing manual workflows, and improving internal processes through practical digital solutions. Focus areas: C#, .NET, C++, MFC, SQL, Windows applications, interfaces, data processing, and internal business tools.

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.

How can I help?

Modernize existing software

I support the porting, refactoring, and step-by-step modernization of existing Windows and business software — without unnecessary full rebuilds.

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.

Further develop processes and systems

Analyze, stabilize, and systematically further develop existing applications, data flows, and internal processes.

Special Topic

Digitalize processes instead of managing inefficiency

When Excel spreadsheets, emails, and manual routines take up too much time, I help analyze, simplify, and digitally map your workflows — with practical software that noticeably eases day-to-day work.

Practical examples from real workflows

These examples show how individual software can support concrete business tasks – from accounting and planning to quality management and mobile data capture.

Accounting Payment reconciliation, dunning and accounting export integrated. Staff scheduling Digital support for duty planning, availability and operational scheduling. Certifications & audits QM processes, evidence and corrective actions managed transparently. Mobile data capture Scanner solution with offline use and later synchronization.

Special Topic

Interfaces & System Integration

Connect and extend ERP, SAP, APIs, web services, devices and technical systems reliably.

Typical situations

Existing software works but is technically outdated
Many workflows depend on Excel, emails, or manual intermediate steps
Data is entered multiple times or manually transferred between systems
Internal processes have evolved but are not cleanly digitized
No one on the team truly knows the existing system anymore
An experienced developer is needed for a legacy system
