7 Basic Principles of Software Development: How to Become a Great Programmer

Now that you know a little about Spring and JPA, what should you study and how to grow in the future? Are you studying design patterns to study design and just memorizing the patterns? I'll help you!

We present various clean coding techniques.

Learn how to add tests to Spring! Then, learn how to change the Spring design to make testing more natural.

Riverpod 3.0 is no longer just a simple state management tool. It represents an evolution into a new paradigm presented by Riverpod's creator, Remi Rousselet: a Data Synchronization Framework. This course boldly skips the listing of basic theories and is designed to help you perfectly master the groundbreaking changes and new features of Riverpod 3 in just 5.5 hours.

Master the complexities of React development, including custom hooks, TDD, the context API, refactoring, and complex state management.

This course is for anyone who is curious about developing test automation on Android and iOS devices. This course will enable you to perform automated testing on mobile devices.

This is a job-oriented QA practical course for beginners preparing for QA employment, where you will complete test cases and checklists used directly in the field by designing and performing tests yourself using real service examples.

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)

Regardless of the field! This is a lecture that covers the core fundamentals that developers must know in practice in an easy + code-oriented way. I highly recommend this lecture to all junior developers and job seekers who want to grow.

Learn various design principles needed to write object-oriented code, focusing on working code.

By developing a simple ReactNative app using the TDD methodology, you will learn the concepts of TDD and practice applying them to ReactNative mobile app development.

If you are a student or developer who is using or studying the Java programming language, you will learn various methods of testing your applications that you must know.

We will develop a banking application using Spring Boot. This course will help you learn how to build an application by testing various problems that arise during development using JUnit.

I have summarized the steps required to get a job as a front-end developer into 7 codes. I didn't have a senior developer, so I was vague when I was looking for a job, but don't worry anymore. 😀

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

Alongside reading, writing, and arithmetic, computational thinking is a skill that everyone living in the AI era must possess. Computational thinking can be simply defined as thinking like a programmer or thinking like a computer scientist. This course faithfully reproduces an actual university semester-long course and covers essential content for those encountering programming for the first time or beginners planning to major in computer science. It also helps non-computer science majors and people with humanities backgrounds develop the ability to communicate easily with professional programmers. Even in an era when we need to learn prompting for AI vibe coding, this course helps learners develop the ability to give AI more accurate and effective instructions through computational thinking.
