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. 😀

Non-majors and beginner developers can easily learn Java grammar. It is a method of learning grammar by analyzing examples.

This course approaches 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 transition 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 not just at knowledge acquisition, but at elevating your way of thinking about distributed systems to the next level.

Build a solid foundation and confidence by developing a variety of topics from scratch with JavaScript.

This is an introductory course that focuses on learning TypeScript's core syntax through hands-on practice to improve type safety and code readability. You'll learn through real code examples, from project environment setup to interfaces, generics, and utility types.

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

When learning Swift, the iOS programming language, it can be confusing when multiple concepts appear all at once. That's why I created this course with the principle that "when understanding a new concept, only previously learned concepts should be used." So this course is meticulously designed with a sequential structure between concepts, where only one new concept appears at each stage, and no other unfamiliar concepts appear at all. One concept per minute, 180 concepts total. From the basics of variables and constants to understanding memory structure from a CS perspective, and even the latest syntax for asynchronous processing. In 3 hours, you'll learn 180 core concepts in the designed order.
