"Developer Portfolio Completion Practice for IT Job Seekers" is a practical course designed to transform projects created in class from simple outputs into portfolios and interview materials that can persuade recruiters. It covers step-by-step how to organize projects, design the first page, expand case studies into structured formats, and connect these elements to interview answers, application routines, and operation/improvement records. This course is particularly suitable for graduates and entry-level developers who have created a portfolio but lack confidence in it or feel lost about what to do next. Through this course, learners will move beyond simply having "made something" and learn how to reconstruct their projects into "documents and evidence that can be utilized for employment."

While LLMs are currently transforming the development environment, what truly matters is not just "writing code on your behalf" but integrating them as features into a service. This course provides a step-by-step guide to implementing a lightweight yet polished Tarot reading service using Next.js and the OpenAI API. In the first stage, we will build an MVP that works without a backend, connecting the user input flow (questions/threads/card selection) to result generation. In subsequent stages, we will expand the functionality by building a backend, implementing general login and OAuth, adding community features, and creating a reading dashboard. Finally, we will conclude by deploying to AWS and integrating Google AdSense to complete a service ready for actual operation. Additionally, we will cover understanding pricing structures and cost optimization strategies to ensure that LLM API usage costs do not become a burden.

This is a 'practical, hands-on lecture' where you can understand the cloud through everyday examples that anyone can easily grasp and learn how to build infrastructure, just as it was conducted in our offline classes.

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.

This course is designed to help you learn the basic concepts of algorithms through JAVA programming. Rather than stopping at simple theoretical explanations, it is structured so that you can naturally understand various algorithms by implementing them directly in code. Students will learn step-by-step, starting from basic sorting and searching algorithms to more advanced ones, while simultaneously developing problem-solving skills and programming logic. Furthermore, by integrating JAVA syntax and usage through practice-oriented learning, you can master both algorithm theory and practical implementation at the same time. Through this course, learners will not only establish a solid understanding of algorithms but also acquire the capability to implement them using JAVA, gaining practical programming skills that can be applied to academics, employment, and professional work.
