"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."

This course goes beyond simply teaching you how to use Docker as a tool; it approaches the subject from the perspective of solving the real-world dilemmas and problems encountered in professional practice. From unpredictable errors caused by differences between development and production environments, to configuration mistakes stemming from vague concepts of images and containers, and even the anxiety of "how much do I need to know to survive in the field"—this course explains it all based on firsthand experience operating financial infrastructure. Rather than just listing commands, it focuses on real-world cases: why certain structures are necessary, how to design images for easy maintenance, and how to handle containers for stable service operation. In particular, by prioritizing hands-on practice over theory, the course is designed to elevate students from simply "knowing how to use" Docker to "understanding it from an operational perspective" through visual comprehension and direct experience. This course provides practical standards and direction for those new to Docker, those who have used it but lack a clear conceptual grasp, and developers looking to take their infrastructure intuition to the next level.
