1) Dozer is a tool that allows users to connect any data source and instantly create low-latency APIs through a simple YAML configuration file. 2) The basic architecture of full-stack development involves a frontend layer for user interaction, a backend for fetching and processing data from databases, and an API to act as a data carrier between the frontend and backend. 3) With Dozer, developers can create backends more quickly by generating APIs through a YAML file that takes only 10 minutes to learn, rather than spending weeks or months developing backend logic from scratch.
