I will develop, fix, maintain, or upgrade your delphi and cpp desktop application


About this gig
Do you need a custom Windows application built, or do you have legacy software that needs fixing, maintaining, or modernizing? With over two decades of software development experience (C#, C++, Delphi, VB.NET) - including 10+ years working directly with Delphi/RAD Studio (Delphi 7 through RAD Studio XE7) - I deliver reliable, high-performance solutions.
Real example: I maintained and extended a 10+ year old Delphi/C++ ERP desktop application used daily in production, adding new modules, fixing critical bugs, and connecting it to a modern SQL Server backend - without breaking existing workflows.
My Services:
- Custom Windows Desktop Software Development
- Bug fixing and refactoring legacy code (Delphi, MFC, VB)
- Database connectivity (SQL) and local file management
- API integrations for desktop apps
- Migrating legacy Delphi/C++ apps toward modern .NET or web
I deliver optimized, secure, and user-friendly software with clear communication throughout.
Have a legacy codebase you are not sure what to do with? Send me a short description of your application and its main pain points, and I will tell you exactly what it needs.
