Social Campaign Analytics Web App

I need a web application that lets me dig into the performance of our social‐media campaigns in one place. The core of the build is the analytics layer: the system must pull and process Engagement metrics, Ad performance data, and Follower growth figures, then present them in clear dashboards and exportable reports.

Role-based access is required. An Admin should be able to connect or disconnect accounts, adjust settings, and manage users, while a Viewer must have read-only access to the analytics screens and downloadable reports. I do not need additional roles for now, but the architecture should make it easy to add them later.

Although we run campaigns on several platforms, I’m flexible about which APIs you start with as long as your codebase is modular; adding new platforms should feel like plugging in another data source rather than rewriting the app.

Key deliverables
• Secure, browser-based app with responsive UI
• API integrations and automated data refresh logic
• Dashboards summarising engagement, ad returns, and follower trends
• Role management (Admin / Viewer) with proper permissions
• Clear setup, deployment, and hand-over documentation

Please outline your preferred tech stack, how you will structure the data layer, and any analytics or charting libraries you plan to use. I’m aiming for a clean, maintainable solution that can scale as our reporting needs grow.
