Omnichannel Social Media API Integration

I need a senior engineer who has already wired multiple social networks into a single product and can show live links or repos that prove it. My platform must speak to X (Twitter), LinkedIn, Instagram, TikTok, Facebook, Threads, Bluesky, YouTube, Pinterest, and Google Business Profiles.

Scope of integration
• Content posting – scheduled and instant.
• Analytics & reporting – reach, engagement, followers, plus any network-specific metrics you can expose.
• Secure user authentication via each network’s recommended OAuth flow.

Everything has to roll out at once, so I’m not looking for a phased approach: all ten connections have equal priority and need to be production-ready as soon as possible. I can supply API keys and sandbox accounts on day one; you bring the code, clear commit history, and evidence that you have shipped this kind of work before.

Deliverables
1. Clean, tested code (Node.js or Python preferred, but I’m open) that plugs into our existing micro-services architecture.
2. Unified interface methods: postContent(), fetchAnalytics(), authenticateUser().
3. Postman collection or Swagger docs outlining every endpoint.
4. Deployment guide and a short hand-off call once all tests pass.

Acceptance criteria
• End-to-end posting, analytics retrieval, and OAuth flows verified for every platform above.
• CI pipeline runs unit + integration tests with ≥90 % coverage.
• No hard-coded keys; environment-based configuration only.

If your portfolio already includes multi-network API work and you can jump on this immediately, let’s talk.
