Essential Java syntax review before studying Java-based development.

"Are you still modifying your code every time you change the server address?" In professional practice, Development (Dev), Staging, and Production (Prod) environments are strictly separated. However, many developers still manually change variables within a single main.dart file, exposing themselves to the risk of deployment errors. This course covers a 'true professional-grade architecture' that allows you to switch environments instantly just by selecting a build target, without modifying a single line of code.

This course will help you gain more confidence in the code you develop by learning the basics of testing.

We provide CodeTree past exam questions along with algorithms and tips for solving them. Although C++ is used, the course is accessible to those using other languages as it does not rely on libraries. (Python code is provided)

Software quality is a habit! This course will teach you how to become the best programmer that companies want.

Even if you create the same function, the code of a junior developer who has just learned JavaScript syntax and that of an experienced senior developer will be quite different. Of course, even if the results are the same. The reason the latter's code is recognized is because of its well-designed structure and scalability to respond to changes. This lecture will learn about how to create such good code.

"Will you make money just by building an app? No." Vibe Coding is merely a tool; the core is 'profitable planning and strategy.' This course goes beyond simple Vibe Coding technical training to reveal a practical manual for building a revenue automation system, learned firsthand by a non-developer operating 200 apps.

This course clearly conveys the actual roles, value, and realistic employment strategies of the QA position for non-IT majors and job seekers. You will gain the confidence to jumpstart your IT career through QA.
