HTML/CSS Windows Reporting App

I need a standalone Windows desktop application whose sole focus is reporting and analytics. The interface must be built with clean, responsive HTML5 and CSS3; you are free to add JavaScript for interactivity, data manipulation, and charting if that streamlines the build.

Core scope
• Present data in clear tables, dashboards, and printable reports.
• Allow users to filter, sort, and export results (PDF or Excel preferred).
• Run entirely on Windows without requiring a browser—packaging with Electron, Tauri, or a similar framework is fine as long as the final installer is simple for end-users.

What I will provide
Datasets, report requirements, and any branding assets you might need. Configuration details (file paths, endpoints, credentials) will be supplied once we start.

What I need from you
When you reply, link to past work that demonstrates desktop apps—or web apps packaged for desktop—built with HTML/CSS. Screenshots or short demo videos are helpful so I can see your styling and usability standards in action.

Acceptance
The project is complete when the installer runs on Windows 10/11, all agreed-on reports generate accurately, and the UI matches the provided mock-ups across common display resolutions.
