Full Stack Developer React Needed for Analytics Platform Research (Node.js, Supabase)

I'm planning to build a web application for marketing teams and growth managers who run accounts across Facebook, TikTok, and Instagram. The platform will pull data from each platform's API, process it through an analytics engine, and surface insights through a clean multi-tenant dashboard. Now I'm moving into a more detailed research phase and need an experienced developer to validate the technical direction, and create a structured discovery document. This is a desktop/web app, NOT a mobile app. Please only apply if you have web dashboard work in your portfolio. Mobile-only applicants will be ignored. Scope. I need the research to cover all three layers, so I have a validated foundation before any code is written. Data ingestion: recommended pipeline structure for Facebook, TikTok, and Instagram APIs via a pluggable data interface, with PostgreSQL as the primary database and MySQL for auxiliary storage Analytics dashboard: validated approach for cross-platform metrics and trend views on React with JavaScript and TypeScript, using HTML, CSS 3, and Tailwind CSS for the interface AI integration layer: recommended architecture for LLM-powered insight summaries and AI development features, built on Python Multi-tenant architecture: database design for data isolation, RESTful API structure across all modules, and Docker for containerization Behavioral data foundation: schema design for structured logging into an analytics-ready model Later phases (not this contract, but build with them in mind): full AI coaching layer, deeper data analysis features, and expanded integrations including PHP and Laravel for existing backend services.
