Finish Nautical CRM Integrations

My nautical-focused CRM site is about 90 % done. It runs on Lovable with Supabase and a small Node.js backend. What still blocks launch is the third-party marketplace layer: OLX is already sending events perfectly, but Mercado Livre is not. I need the webhook to receive every listing and order event from ML, record them in Supabase, and fire the same notification flow that OLX does. I’ll keep working on security hardening and performance, and I’m happy to hear any UI or design suggestions you spot while inside the code. The immediate goal, though, is a rock-solid Mercado Livre integration. Preferred partner: Portuguese-speaking (Brazil), Mercado Livre API is a plus, Supabase functions, and basic Node/Express. Familiarity with Lovable’s component system will make things faster. Deliverables • Fully functioning Mercado Livre webhook endpoint with auth, signature validation, and retries • Sync routine that mirrors ML events in Supabase in real time, matching OLX behaviour • Short hand-off notes or walk-through so I can maintain it • design suggestions Acceptance test: I’ll publish, edit, and delete a test ad on Mercado Livre; corresponding inserts/updates/deletes. We can start as soon as you’re ready and iterate on smaller polish tasks once the integration is stable.
