Web Report Generator Development

I need a streamlined, browser-based application that lets me create professional reports on demand. Everything should run entirely on the web—no mobile build is required—so users can work from any modern desktop browser without installing extra software.

Core flow
• Upload or connect to a data source (CSV, Excel, or an SQL database)
• Choose or design a report template with charts, tables, and branding elements
• Generate the report instantly as PDF and/or interactive HTML
• Save, download, or share the finished file via a unique link

Key requirements
• Clean, responsive UI built with React, Vue, or a similarly mature front-end framework
• Back-end API (Node, Django, or comparable) that handles data processing and PDF/HTML export
• Modular code structure so I can add new report templates later
• Role-based access ready to plug in, but keep authentication optional for this first release
• Clear developer documentation and a short hand-off call once the MVP is deployed to my hosting

I will provide sample data, logo assets, and access to the hosting environment. Please outline your preferred tech stack, timeline, and any previous web reporting work when you respond.
