When I was in college, I wasn't really interested in service development, but after graduating and joining the military, I thought about my career path and became interested in service development, so I'm studying hard! I was at a loss because I had to learn a lot to become a backend developer, but I'm following Younghan's roadmap and following Spring step by step. Thank you! I'll be discharged in 9 months, but I'll study hard and improve my skills before then to become a backend developer. Thank you for the great lecture ^^
