Experience: Intermediate

The current sttack: React/TypeScript frontend, Supabase backend (Postgres + Deno Edge Functions), and a multi-provider AI narrative pipeline (Gemini, GPT, Claude with race/fallback and cost telemetry), plus cached results, usage limits, and admin tooling. Meaningful foundations already exist: a provenance_kind column, URL trust verification with a nightly audit cron, a canonical repair_product_ingredients RPC protected by a Postgres trigger that blocks direct writes to ingredients, analysis-cache quarantine flags, an ingredient verification queue, an admin-gated repair-drafts table, and nightly hygiene jobs. The work is extending and tightening these, not greenfielding. Catalog is ~9,000 products and will grow to 40k+ products. The app is live with a small number of paying users, very light current load. https://getdare.ai
