Social Media Integration API Website

I’m building a new web-based marketing platform whose core job is to act as a single API layer for the major social channels I use every day. In this first phase I want clean, well-documented integrations for Facebook, Twitter, Instagram, and What’s up so that I can:

• Schedule posts from one central dashboard and push them out at predefined times.
• Pull back concise, real-time analytics and reporting on reach, clicks, and other standard metrics.

The site can be lightweight in design—the priority is solid backend work, clear RESTful endpoints, and straightforward authentication that respects each network’s latest policies. If you’re comfortable exposing those functions through a small admin UI (React or similar is fine) that’s a plus, but the API itself is the real deliverable.

I’m leaving room for future expansion (for example, user-engagement features like likes or comments), so please keep the code modular and well-commented.

When you hand this over I’d like:

• Source code and a quick README explaining setup
• Environment variables documented for the different platform keys
• A short Loom or similar walkthrough showing the scheduling flow and an example analytics pull

If anything is unclear, let me know and we can pin down the specs together.
