+## Summary 💡
 
 Echo is a small web application that lets a user sign up, log in, and manage simple posts (create, read, update, delete). The app demonstrates a typical web product flow: a user-facing interface (frontend) talking to a server (backend) that stores data in a database. It's suitable as a learning project or a starting point for production-ready work.
