This February, I decided to become a service company developer as a non-major. I didn't know any developers around me and I had little knowledge about this field, so I was really at a loss as to what to look for. I happened to find Han Jeong-su's blog and read his 2018 review, which motivated me a lot. After that, I weighed several boot camps and government-funded academies, and ended up attending the government-funded academy, which was the fastest to start, and I am now one month away from graduating. Our government-funded academy conducts two projects over five months: a semi-project and a final project. For a while, I was only able to briefly review the progress of the government-funded academy classes, but after the semi-project, I suddenly came to my senses. This is because I had no roadmap at all on what to prepare for and how to get a job. The government-funded academy does provide job support, but it was all targeted at SI/SM companies, which was different from my goals, so I had a lot of concerns. Then I found this course, paid for it right away, and completed it. I regret not having taken this course before entering the national academy. I felt that he had prepared the course very diligently, and the materials provided through the link were very helpful to me, who knew nothing. If you want to know the overall roadmap for becoming a developer as a non-major, I highly recommend taking this course. After taking this course, I recommended it to my fellow students at the national academy and friends around me, and whenever I feel discouraged, I come back and watch the course again. I would like to thank Han Jeong-su for opening this course.
