Hamid Reza Sharifi

I’m an experienced Software Engineer with a demonstrated history of working in the computer software industry. I received my Ph.D. degree in Computer Software Engineering from Islamic Azad University, Science And Research Branch in 2018. Over the past few years, I have been working mainly on projects built around Java, Spring Boot, Agile Methodologies, REST API, Microservice, and Keycloak IAM. Also, I’m very interested in learning new technologies and the latest practices in the industry.

Here's what I've written (so far):
