I want to add fresh, useful functionality to my Facebook presence and need an expert who already knows their way around the Meta developer ecosystem. We will start by discussing the exact pain points and opportunities, then move into designing and building a solution—whether that ends up being a lightweight in-page widget, a custom app, or another approach you recommend. You’ll be expected to: • Validate the idea against current Facebook Platform and Graph API policies. • Produce wireframes or mock-ups so I can sign off on the user experience before coding starts. • Build the feature, test it on desktop and mobile, and hand over clean, well-commented source code. • Provide a short deployment guide so I can maintain or extend the solution later. Please highlight previous Facebook or Meta-related projects when you reply, especially ones that involved UI tweaks, custom integrations, or privacy-sensitive data handling.
