ABOUT ME

Java and Spring microservices developer

Hi, I'm a young guy currently in love with Java ☕ and everything around microservices architecture including Docker 🐋 and automation. So I try to automate most of my repositories or at least include a simple CI pipeline. I would like to get more familiar with React or Angular, however, my heart sticks with backend.
