We are looking for an experienced full-stack developer for a one-time, fixed-scope project: building a data dashboard that tracks social media performance (YouTube, Instagram, Facebook, TikTok) across multiple client accounts.

This is not an ongoing role. It is a single project with a clear deliverable, targeted for completion by end of August.

What the dashboard needs to do:

• Pull data from YouTube Data API + YouTube Analytics API, and Meta Graph API (Instagram/Facebook Business accounts)
• Store historical data in a database (platforms don't retain long history via their own APIs, so daily data pulls and storage are required)
• Display per-client, per-platform metrics: views, CTR, retention/watch time, follower growth, traffic sources
• Integrate a link-shortener API (Bitly or Rebrandly) to track click-through leads per video/post
• Generate automated weekly reports comparing current performance to historical averages

• Support OAuth account linking per client, per platform (each client connects their own account)

   

We will provide a full written specification of required metrics, dashboard structure, and reporting logic before work starts.

What we need from you:

• Proven experience integrating third-party OAuth APIs (Google APIs, Meta Graph API, or similar), not just building internal REST APIs
• Experience with scheduled/cron jobs for recurring data collection

• Comfortable owning a feature end-to-end: database schema, API integration, frontend display, deployment

   

Please include in your application:

1. A specific example of a project where you integrated an OAuth-based third-party API (name the API, describe how you handled token refresh and authentication)
2. Whether you've built a system that pulls and stores data from an external API on a recurring schedule (not just on-demand calls)

Applications without a concrete example of #1 will not be considered, regardless of general stack experience.
