Build and deploy community applications using the MERN Stack (MongoDB, Express, React, Node + Firebase)

Starting with the question, "If I were on the Titanic, would I have survived?", this course completes a full-stack project where you develop an AI model to predict survival probabilities based on real data and deploy it as a web service. You will gain hands-on experience in the entire process of AI and web development, from deep learning modeling using PyTorch to building a backend server with FastAPI and implementing a user interface with Next.js.

Now it’s time to take on a real-world project 🔥 Together, we’ll build a production-grade social networking service with React.js + TypeScript + Supabase, implementing features such as authentication & authorization, infinite scrolling, image uploads, likes, infinitely nested comments, and dark mode. Along the way, we’ll also explore server and global state management techniques using Zustand and Tanstack Query.

Learn how to implement integrated regular and social logins using Spring Boot and React. Build a login system in both MPA and SPA environments and practice JWT and OAuth2 authentication. Understand and implement the entire login flow through example projects applicable directly to real-world scenarios.

A portfolio-focused course on deploying a React frontend and Spring Boot backend directly to the AWS cloud! This course is helpful for those who want to quickly deploy frontend and backend projects for their portfolio. You will gain the necessary knowledge for deployment through short-term, step-by-step practice, covering everything from server configuration to Docker, domain connection, Nginx, and HTTPS application!

"A query that ran perfectly during development suddenly slows down as data accumulates." At such times, the mark of a truly skilled developer is identifying the root cause based on solid evidence rather than guesswork, and optimizing a 30-second query down to 0.1 seconds. Master the core principles of database performance—from execution plans, indexes, and optimizers to joins and sorting—using millions of rows of real-world data. Elevate your skills and become a top-tier developer capable of independently analyzing and resolving slow queries in production environments.

Delving into Django's core concepts and key features in detail, from API development methods using DRF to deployment leveraging AWS, this covers everything about Django web development.

This is a profit-oriented practical course where you will directly develop coin/stock automated trading systems and apply real-world trading strategies such as Grid, Moving Average, and Martingale. You will build 24-hour automated trading bots through practical trading exercises using Upbit, Binance, and Korea Investment & Securities (Kiwoom Securities) APIs, along with cloud deployment, while exploring real-world strategies for monetization. #Quant #Bitcoin #Algorithm #Investment #WealthManagement #AutomatedTrading #Bot #Agent #AI #OpenClaude #ClaudeCode

A FastAPI course for modern full-stack and backend development that is easy to use and delivers high performance. It covers backend concepts step by step, the core syntax of FastAPI, and asynchronous database usage, all organized clearly through well-structured materials and projects.

Based on the experience of wondering how facial recognition works in offline environments on-site, this course will guide you through building the basic structure of a facial recognition-based access and attendance management system using React + Electron and Python's FastAPI-based DeepFace. Rather than focusing on perfection, we focus on understanding the operating principles and laying the foundation for you to expand into your own personal projects.

★PYTHON★ This is a basic lecture on server development using Fast API. Learn how to develop servers easily, quickly, and conveniently using various packages such as Fast API, SQLAlchemy, Pydantic, and Starlette! Don't worry, we have prepared a DB backup file as well as integration with PostgreSQL! We will teach you the "basics" of UI design using Dash and Plotly and provide the source code used in the lecture :)

Build a fully functional smart farm platform that integrates sensor data collection, MQTT communication, web dashboards, and AI-driven environmental analysis. Experience the entire process of agricultural digital transformation (DX) through a hands-on project, covering everything from IoT sensor integration and FastAPI/Spring-based API servers to React/Vue dashboard development and cloud deployment.

Developing an AI Safety Report Service with React + Spring AI The 5th Neo + Essential project lecture is about building a Safety Report system, an idea for improving government systems!

You can learn the basics of React. You can organize HTML, JavaScript, DOM, Event, Object, Module, OOP, etc. related to React.

Docker, a technology stack used by over 20 million developers worldwide! We'll study Docker and container concepts, which have become essential technology stacks for countless developers, by following the official documentation! I think you might have been intimidated before even starting when looking at the thick Docker books among the technical documents available in the market. This course is structured with a solid curriculum focused on hands-on practice, highlighting core content based on Docker's official documentation. I promise that this course will help you quickly apply Docker in real-world scenarios! After completing the course, you'll be able to use Docker in various practical ways!

"Next.js Master Class: Part 3 - Completing Real-World Architecture" goes beyond tutorial-level projects that only run locally; it is a guide to designing "real production" architectures capable of handling massive traffic. It covers all the core technologies used in the industry, from flawless state synchronization combining TanStack Query and Zustand, to Turbopack-based bundle optimization under 100KB, advanced SEO injection, and building ironclad full-stack security networks using proxies and JWT sessions. I strongly recommend this course to those who want to overcome tedious hydration errors and CORS barriers on their own, moving beyond being a simple coder to becoming a "Senior Architect" who commands the entire frontend system.

Real-world practice is harsh. I will perfectly pass down my essence of optimization—designed to maintain a smooth user experience even in extreme environments where tens of thousands of real-time data points pour in—through a meticulous mission system. Go beyond simply being someone who writes code and leap forward into an irreplaceable senior engineer who orchestrates performance through the principles of the engine.
