I’m looking for a sharp full-stack developer who can wire Facebook, Twitter, and Whatsapp straight into my application so users can share content with a single click. Here’s what I need: • Integrate the latest Facebook Graph API, Twitter API v2, and the official Whatsapp Business Cloud API. • Build secure backend endpoints that manage tokens, permissions, and rate limits. • Add a simple front-end control (button or modal) that triggers the share action and returns clear success/error feedback. • Log each response server-side for troubleshooting. • Deliver well-commented code plus a short README so I can reproduce the setup in staging and production. Acceptance checks: – One demo page that posts a fixed message and link to all three platforms. – OAuth flows run over HTTPS with no secrets hard-coded. – Documentation lists required environment variables, build steps, and any API keys. I’ll supply repository access and the app credentials. If you’re comfortable pushing via Git and can turn this around quickly, let’s get started.
