Master complex Flutter state management in just 3 hours.

This is a comprehensive lecture on Kotlin grammar that can be learned in 1 hour.

"Are you still modifying code every time you change server addresses?" In real-world practice, development (Dev), staging, and production (Prod) environments are strictly separated. However, many developers are exposed to the risk of deployment accidents by manually changing variables in a single main.dart file. This course covers a 'real production-grade architecture' that allows you to instantly switch environments simply by selecting a build target, without modifying a single line of code.

Kevin's Easy-to-Understand Java Developer (Web Developer) Roadmap Story

This is a course on understanding Java design patterns. It helps you learn about various design patterns and increase your understanding of design patterns. A course that explains Gof Design Pattern in Java. I tried to prepare meaningful and easy examples.

This course is a video lecture that systematically covers the core modern JavaScript syntax essential for learning React.js and Vue.js frontend development. It is structured to help you develop efficient coding skills through ES6+ syntax, latest features, and practical examples that can be directly applied to work and learning.

A Java advanced project course for beginner developers who want to develop practical skills! We'll build a console-based kiosk ordering system together using Spring Core, JdbcClient, and H2 DB.

Learn SAGA transaction management techniques for maintaining data consistency in distributed environments through hands-on practice. Build 3 microservices using Spring Boot and Docker, and implement both Orchestration and Choreography patterns with Kafka and MySQL. Through this course, you can master core concepts that are immediately applicable in real-world scenarios, including distributed transaction operation principles, compensating transaction design, and failure recovery handling.

This course will help students understand Java classes in more detail and use them more naturally. This will lead to more object-oriented programming.

Through training in thinking, expressing, and coding, you can easily understand and approach Java programming. You can understand the relationship between programming elements and gain confidence in future Java API utilization and projects through precise concept organization of object-oriented programming.

This course explores microservice architecture and distributed environments not as a simple list of technologies, but from a 'design perspective' required in actual work and interviews. Starting from the differences between monolithic and MSA, it progressively covers incremental migration strategies, modular monoliths, clean architecture and hexagonal architecture, clearly explaining why each choice is necessary and the trade-offs involved. Through hands-on practice, you can directly verify the intent of the structure and learn about core issues inevitably encountered in distributed environments—such as data consistency, transactions, inter-service communication, and failure handling—through realistic scenarios. Based on actual questions and perspectives from Kakao interviewers, this course aims to go beyond simple knowledge acquisition and elevate your way of thinking about distributed systems to the next level.

Java is not difficult to learn. It's just that it becomes difficult because you learn too many unnecessary things. There are things in technology that can only be understood when you reach that stage. But, it's just hard because you try to cram too much unnecessary stuff into your head. Technology is experience. Let's learn quickly and simply!!

This is a lecture for people who are starting development for the first time. It's about programming thinking, which should come before development languages or UI frameworks.

<25 English Technical Interview Questions and Answers by Local Australian Java Developers> is for all those who want to work as Java language programmers. Since Java language is a computer language that is constantly in demand worldwide, this lecture will be a useful guide for preparing for actual interviews not only for those who want to work overseas but also for those who want to work domestically.

This course prepares you for the Information Processing Engineer practical exam solely through solving past exam questions. Instead of unnecessary theory or extensive content, it's designed to lead directly to 'passing' by focusing on past questions that repeatedly appear on actual exams. It reflects the latest exam trends, allowing you to quickly grasp key points and question patterns, and you can learn answer-writing techniques through the problem-solving process. This is a course optimized for test-takers aiming to pass efficiently in a short time.

Currently, Android can be developed using the Java and Kotlin languages. The same Android application can be developed using either language. This course covers most of the content from basic to advanced Android application development, and all code is written using the Kotlin language starting from the basic content. We also use Material 3, Google's latest UI library. This course mainly covers menus, Android application components, threads, and Fragments among the entire Android curriculum, and future courses are planned to cover more in-depth topics. Soft Campus will always strive to provide the latest lectures. Thank you.

Pass the Information Processing Engineer Practical Exam in one shot! We'll pinpoint exactly the essential code and theory you need. Master past exam questions perfectly! Open the door to success with systematic lectures.

Hear essential insights for developer career growth from the top 1% of developers.

Software development roles in the defense industry: ✔ Have different hiring criteria compared to general IT companies ✔ Use specialized tech stacks and development methodologies ✔ Offer very little information on how to effectively highlight your major, career, and projects. This course: 👉 Provides the perspective of a software developer who has experienced actual defense projects and hiring processes 👉 Explains how defense companies evaluate software developers 👉 Focuses on specific case studies to show you how to prepare your resume, interviews, and projects to increase your chances of success. This course transforms the state of "wanting to become a defense software developer but having no idea what to prepare" into a "clear roadmap you can start following right now."
