At my company, while I was an intern and then got a full-time job, I'm not using the spring framework I had been studying, but rather developing apps with ruby on rails + framework7. Despite this, I still want to continue studying spring jpa, so I'm listening to Younghan's lectures from time to time. This is the first lecture of the roadmap completion goal ^^ If I get the chance, my goal is to create a side project based on spring jpa before all roadmaps are finished!! Thank you for the great lecture. I'll look forward to it in the future!!
