🚨 Your database query works… but it’s taking 3 seconds? Before rewriting the whole backend, check your database indexes. One missing index can turn a fast query into a slow one as your data grows. Optimize the query before optimizing everything else. ⚡ Have you checked your database indexes recently? 👇

Your Supabase app is working… but your database is still exposed? 🔐 One mistake I see developers make is setting up authentication and forgetting about Row Level Security (RLS). If you're using Supabase, don't just create your tables and move on. Make sure you: ✅ Enable RLS on your tables ✅ Create policies for who can read data ✅ Create policies for who can insert or update data ✅ Never expose sensitive service keys in the frontend ✅ Test your policies with different user accounts Authentication tells you who the user is. RLS helps control what they can access. Have you ever had an RLS policy block something that should have worked? 👇
