These days, when the development market is in a slump, what do I need to experience a differentiated project that is better than others as a new backend developer? I thought about it countless times. I received mentoring and bought several Inflearn courses, but I was indecisive until I received a notification that this course was available, and I immediately took the course. When connecting to a technology or external API, the instructor provided recipes for creating a good project, not just implementation, but also troubleshooting and better performance improvements, so I think I will be able to create a better resume and portfolio 😊😊
