Скачать или смотреть Day 4 | Build With Me – Backend Setup for Login & Signup

In Day 4 of this Build With Me series, I shift focus to the backend and start implementing the login and signup flow.

In the previous video, we completed the frontend. In this one, I set up the Spring Boot application and build the backend step by step using Kotlin — defining controllers, services, and repositories, and wiring everything together properly.

This video is about laying a clean backend foundation, not rushing into advanced features.

🔧 What’s covered in this video:

Setting up a Spring Boot project with Kotlin

Understanding the Controller → Service → Repository flow

Writing login and signup logic in Kotlin

Structuring backend packages properly

Connecting the backend flow with the existing frontend

🛠 Tech Stack:

Backend: Kotlin + Spring Boot

Frontend (previous video): React + TypeScript

Database: PostgreSQL

If you’re new to Spring Boot or confused about how real-world backend projects are structured, this video will help connect the dots.
