Stabilizing business software, digitizing processes, and developing practical tools

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.

I also support smaller companies with simple websites, web solutions, desktop applications, and small tools when workflows need to become easier, clearer, or less error-prone.

Three typical starting situations

Many companies know that a process should work more easily – but not which technical solution is needed. That is not a problem.

You do not need to bring a finished specification. Often, a short description is enough: What takes time today? Where do errors occur? Which task is repeatedly done manually?

I support companies with simple homepages, web solutions, small desktop programs, data and Excel tools, interfaces and the further development of existing software.

Homepage & web programming

For small companies, self-employed professionals and businesses that need a simple, professional website or want to modernize an existing homepage.

Examples:

  • Company website
  • Contact form
  • Service pages
  • Simple web applications
  • Small customer or inquiry areas

Small tools & desktop programs

For recurring tasks, Excel lists, data checks, file imports, exports or small administration programs.

Examples:

  • Read and check Excel files
  • Automatically convert data
  • Create labels or PDFs
  • Compare price lists
  • Small customer or order management

Existing software & interfaces

For companies with existing programs, databases or grown systems that need to be extended, stabilized or modernized.

Examples:

  • Existing Windows applications
  • Databases
  • Interfaces
  • Import and export
  • Modernization of old programs

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.

Develop small tools and web solutions

Targeted implementation of web forms, small desktop applications, and practical helper tools for recurring tasks, data processing, and simpler internal workflows.

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.

Special Topic

C++ / MFC Modernization

Support with analysis, stabilization, maintenance, and step-by-step modernization of mature Windows applications.

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.

Special Topic

Interfaces & System Integration

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

Typical situations

When existing software is involved

  • Existing software is still running, but technically outdated
  • No one in the team really knows the existing system well anymore
  • An experienced developer is needed for a grown legacy system

When workflows are manual

  • Many workflows depend on Excel, emails, or manual intermediate steps
  • Data is entered multiple times or transferred manually between systems
  • Internal processes have grown over time, but are not properly represented digitally
