Backend is no longer difficult!
Complete it in a flash with Supabase.

In the AI era, being a frontend developer alone is not enough. When trying to create your own service or implement AI features, you often hit the massive wall of the backend. Database design, user authentication, storage management, and complex infrastructure setup... there was so much to learn that it felt overwhelming, right? This course was prepared for people like you. We provide the fastest shortcut to becoming a full-stack developer who can "quickly" build a backend with nothing but Supabase without complex server knowledge and implement your ideas immediately.


When you need to start studying backend development for service expansion, but feel overwhelmed by how much there is to learn and don't know where to begin.

When you are tired of repeatedly implementing the same backend features (user authentication, DB, storage) every time

When it takes too long to prototype your own ideas

This course is not just about teaching you Supabase.
It is a course that will help you establish basic concepts of the Backend. Cloud services like AWS are overly complex for beginners to study. In contrast, with Supabase, you can start backend development immediately just by knowing the basic concepts. I will explain everything starting from backend concepts (HTTP, DB, network, CDN, login, etc.)!


The moment a frontend developer transforms into a full-stack developer,

Supabase!

I will show you the fastest shortcut to
quickly complete your own service without worrying about
complex DB design, authentication, or infrastructure.

By the end of this course, you will


quickly complete your backend with Supabase.

  • You will learn how to build your own service from database design to API integration in just a few hours by leveraging the powerful features of Supabase, without complex server management or infrastructure setup. This is the ideal course for solo developers or entrepreneurs who want to prototype their ideas immediately.

Equip yourself with the full-stack development capabilities required in the AI era.

  • Even as a frontend developer, you will recognize that backend knowledge and concepts are essential for creating your own services or integrating AI features, and you will learn how to solve this easily and quickly through Supabase. Put an end to the worry that "frontend alone is not enough" and upgrade your service implementation skills to the next level.

Perfectly implement the headache-inducing authentication (Auth) system.

  • You will learn how to implement complex and time-consuming authentication features—such as email login, OAuth integration (like Google Login), OTP authentication, password changes, user profile management, and token reissue—with just a few lines of code using Supabase. You will become an expert in building secure and convenient authentication systems that do not compromise the user experience.

Gain the confidence to deploy services without complex infrastructure management.

  • Supabase completely relieves the burden of building backend infrastructure, such as server deployment, database management, and storage setup, which may have felt difficult. In the latter half of the course, you will experience implementing and deploying serverless functions using Edge Functions, gaining the practical skills to quickly bring your ideas to the world.

Why this course is the fastest solution

Build a Backend in No Time
with Supabase

Have you felt overwhelmed by the increasing complexity of backend development in the AI era? In this course, we will show you how to quickly and easily implement complex backend features, such as database design, user authentication, and storage management, using Supabase.

Hands-on! Supabase Integration and API Construction

We will design tables and columns using Supabase's ORM based on Node.js and connect 1:1, 1:N, and N:M relationships. Additionally, you will learn essential knowledge for database operations by practicing RLS and trigger settings, as well as migrations.

Implementing a Secure and Fast Backend

You will directly implement powerful authentication systems such as email and Google OAuth login, and learn how to upload and manage images using storage features. Furthermore, you will implement serverless functions through Edge Functions and learn how to deploy services without complex infrastructure.

For your information, my teaching style has changed significantly starting with this lecture. Since we are in the AI era, I will no longer conduct lectures where I code live and expect you to just type along. Because the ability to ask AI "well" and command it "well" is the most important skill, I have shifted the direction to focus on explaining fundamental concepts so that you can handle AI more effectively. Additionally, I plan to include missions throughout the lecture (and increase them gradually) that require you to think and solve problems on your own, moving away from passive watching toward a more hands-on learning experience.

If you have an idea, you're all set!
Backend Completion Roadmap

Let's start by establishing a clear understanding of database concepts.

Section 1

Introduction to Supabase and Database Basics

We cover Supabase project creation and basic configuration. Understand the core database concepts of tables and columns, and learn various relational modeling techniques.


Let's manipulate the DB with JS/TS

Section 2

Supabase ORM and Database Integration

Learn how to interact with databases using an ORM. Master database management and manipulation techniques, including CRUD operations, JOINs, migrations, and transactions.


You can also easily integrate things like Google Login.

Section 3

Implementing Authentication Systems

Learn the basic concepts of user authentication and directly implement a secure authentication system using email login, OAuth (Google), and OTP. It also covers user information management and token reissue methods.


Let's upload an image to Storage, which serves as our file repository.

Section 4

Storage Management and CDN Utilization

Set up and utilize Supabase Storage for uploading and managing files such as images. Learn how to configure bucket policies, generate access URLs via CDN, and implement upload and download functions using signed URLs.


If you need to write backend logic, use Edge Functions.

Section 5

Edge Functions and Serverless Implementation

You will learn how to implement serverless logic using Supabase Edge Functions. We will proceed step-by-step, covering HTTP request and response handling, local testing, and deployment to a live server.


It's a Kanban board where content is updated in real time.

Section 6

Final Project

We will carry out a real-time collaborative Kanban board project that integrates everything you have learned so far. There are also missions included, so try implementing them with the help of AI.


Bonus: Learn the concepts of additional Supabase features such as AI Vector, Cron, and Queue and understand how they are utilized.
