ERP Knowledge Upskilling

For a while now since I am currently working as a backend developer on a ERP project for AVEGA Bros. my current employer, I have been seeing spring boot for a while and since I'm already in an ERP ecosystem why not use it to expand my current knowledge, ideas, and interest's in development. Since I am actively doing side projects currently hobbies or intentional projects just to grow what I currently planted, while I did my research with Spring Boot I just learn it uses Java as its language and as I dig deep it also has controllers, repositories, services, dto's, entities etc. same boilerplate's as NestJS since now I can say I am familiar with decorators, services, controllers, entities, dtos, and repositories with NestJS as main framework for my backend development. As I look for more information's the learning curve is steep but I also start here when I was just learning NestJS but it did not stop me from learning, maybe the phase was slow but it was consistent and I was persistent each day time's passes by the confidence grew in me and that's when I learn and find out I think it's time for me to expand out and upskill, while continuously growing with NestJS I am also trying to grab another understanding that will be my leverage as time goes by. So yeah, this will be a new journey for me and I will be building new projects based on what I have learned, as usual hobby or intentional projects I will build.
