Add Social Media Sharing Feature

I need a developer to extend my current product with a fully-functioning social media sharing feature. The goal is simple: allow users to share selected content straight to their preferred networks quickly and reliably, without disrupting the existing experience.

Here’s what I expect:
• A clean, intuitive share interface that fits the current UI
• Support for the major platforms covered by each network’s latest API (Facebook, X/Twitter, Instagram, LinkedIn at minimum)
• Proper handling of user permissions, callbacks, and error states
• Lightweight code that will not slow page or screen loads
• Clear hand-off documentation so I can maintain or expand the feature later

Once built, I’ll test cross-platform functionality and review code quality. If everything works smoothly and the integration is seamless, that will be the acceptance criteria for completion.
