Windows Data Management Tool

I need a standalone Windows desktop application that lets end-users store, search, edit, and export structured data without having to rely on a web connection. The core focus is efficient data management, so a responsive UI, fast look-ups, and rock-solid read/write integrity matter more to me than flashy design.

Key capabilities I’m after
• CRUD operations on user-defined records (add, duplicate, edit, delete)
• Flexible search and filter (by any column, partial matches, date ranges)
• Import from and export to common formats such as CSV or XLSX
• Simple reporting or printable summaries (PDF or direct print)
• Local database file that can be backed up and restored easily

I’m comfortable if you build it with C#/.NET (WinForms or WPF), but I’ll consider other Windows-native stacks provided everything installs cleanly with a single MSI or EXE. Please include well-commented source code, a short setup guide, and a quick user manual so I can hand it off to non-technical staff.

Acceptance criteria
1. Installer runs on Windows 10/11 without extra downloads.
2. All listed features work as described with test data I will provide.
3. No unhandled exceptions during normal usage.
4. Source compiles in a clean environment and matches the delivered binary.

If this sounds like your wheelhouse, let me know how you’d structure the project and a ballpark timeline.
