🔥 This is a practical full-stack course where you implement the entire journey a student experiences, from browsing lectures to payment and deployment. You will build everything yourself—including lecture search, detail pages, enrollment, video playback, reviews and Q&A, shopping carts, actual payments, "continue watching" features, and Docker + AWS deployment—to master user flows and architectural design close to real-world services and complete a high-level full-stack experience.

🔥 This is a practical full-stack course where you will implement the knowledge-sharer features from scratch, from course registration to video uploading. Using Next.js 15 and NestJS, you will follow the actual Inflearn workflow—creating courses, organizing curriculums, uploading thumbnails and videos, and writing detailed descriptions—while gaining hands-on experience in Prisma modeling, JWT authentication, S3 + CloudFront uploading, and Swagger API design.

You can learn how to send emails using AWS and Spring. Through this, you can study how to create an email verification system.

It doesn't end with just creating one application. We will show you the A-Z of completing a service by connecting a Vue.js modern front-end stack to a backend using Spring Boot.

In this lecture, you will learn about AWS ECS, one of the representative technologies of Container Orchestration! You will also build CICD with Github Action. However, you will not learn ECS from the beginning. ECS can be called the king of DevOps, so it can feel too difficult. So, in the beginning of the lecture, we will first cover the basics with AWS Lightsail, which has a relatively low learning curve among traditional virtual servers. You will also experience the limitations and inconveniences of the existing method. By building up with the basics and “Why” in this way, you will naturally learn Docker Containers and ECS!

Through this course, you can prepare for the AWS Certified Solutions Architect - Associate certification and learn about AWS services in general.

The most definitive practical guide for job seekers and junior developers new to CI/CD automation! You will perfectly master everything from building CI/CD pipelines using Jenkins to creating production-level automated deployment environments integrated with AWS infrastructure (S3, ECS).

This is a basic course on web development using Blazor WebAssembly. Learn how to easily do DB CRUD using EntityFrameworkCore. We will teach you the "basics" of Razor Page UI Design. We will also provide the source code used in the course :)

Have you wanted to implement RAG but felt overwhelmed by connecting everything from embeddings to vector storage and search? Based on real-world service development experience, this course explains the core concepts of pgvector and the service source code. By calling the API directly, you can quickly understand the entire flow of how RAG vector search works.

This course is a practical-focused learning program for JWT-based token authentication and security enhancement techniques that are essential in modern web service environments. Using Spring Boot 3, Spring Security 6, and React, you'll implement secure login systems and cover comprehensive security practices including XSS·CSRF countermeasures, HTTPS implementation, token reissuance and revocation strategies, and secure secret key management. Additionally, you'll practice real service-level environment configuration through AWS build·deployment and performance optimization using Redis, and the complete project source code provided in the course can be directly applied to real-world work.

I've created a cram course that will help you pass the AWS SAA-C03 (AWS Certified Solutions Architect - Associate) certification in just 2 weeks with only 163 questions!

In this course, you will be able to create a Reddit website from scratch, step by step.

How are you using TypeScript, the standard of Node.js? If you only add type annotations, it is not real TypeScript. I prepared everything because I don't know what you will like. Let's learn TypeScript A to Z :)

This course goes beyond simple CRUD-level database usage to help you acquire PostgreSQL skills necessary for the AI era from a practical perspective. Based on AI development experience in Silicon Valley, you will learn step-by-step how to design and utilize JSON, indexes, transactions, and even pgvector in real-world services, while mastering methods to solve complex data structures and performance issues.

It explains almost everything surrounding the cloud in an easy-to-understand manner. If you listen to it before the actual practice, you will be able to understand development or infrastructure cloud well.

While LLMs are currently transforming the development environment, what truly matters is not just "writing code on your behalf" but integrating them as features into a service. This course provides a step-by-step guide to implementing a lightweight yet polished Tarot reading service using Next.js and the OpenAI API. In the first stage, we will build an MVP that works without a backend, connecting the user input flow (questions/threads/card selection) to result generation. In subsequent stages, we will expand the functionality by building a backend, implementing general login and OAuth, adding community features, and creating a reading dashboard. Finally, we will conclude by deploying to AWS and integrating Google AdSense to complete a service ready for actual operation. Additionally, we will cover understanding pricing structures and cost optimization strategies to ensure that LLM API usage costs do not become a burden.

We will inform you about all the security aspects of migration using MySQL and direct operation of DB Server.

You can quickly experience the process of deploying a sample e-commerce service to AWS and continuously improving it into a robust and efficient environment.
