+## Workflow
+
+The entire application works on a client-server architecture. The backend is requested from the client side using Next.js API routes. Originally, the real backend server is deployed on Render where Leetcode API is called to fetch the data. The data is then stored in a Supabase database. 
+
+On the client side, the data is fetched for the users, problems, submissions, and progress. The data is then displayed in a user-friendly manner using charts and tables. The application is deployed on Vercel for better performance and scalability.
