I will maintain fix and support your legacy dot net vb c sharp desktop application


À propos de ce service
Is your business still running on an old VB.NET or VB6 desktop application that the original developer left behind? You're not alone thousands of businesses (clinics, factories, retail, HR/payroll systems) run critical operations on legacy Windows software that nobody wants to touch anymore.
That's exactly where I come in.
With 5+ years of hands-on experience maintaining a large legacy VB.NET/.NET codebase spanning inventory management, hospital/clinic systems, and HR/payroll software, I specialize in:
- Fixing bugs in existing VB.NET or VB6 applications
- Adding new features without breaking existing functionality
- Database integration issues (SQL Server, stored procedures, performance tuning)
- Reports, exports, and file-format compliance (banking files, EDI, positive pay formats)
- Infragistics UltraWinGrid and other legacy UI component issues
- SFTP/FTP integrations and secure file transfer setup
- Ongoing monthly maintenance/retainer support
I understand that legacy code is often undocumented, messy, and fragile that's normal, and it's exactly what I'm used to working with daily. I won't rewrite your whole system unnecessarily; I fix what's broken and improve what needs improving, carefull
