Hello,
I have been working as a programmer for five years, exclusively with Java throughout this time. My experience spans both new projects and those with over 5 years of history.
I have primarily worked with Java 17, Spring, Hibernate. All of my projects have been designed using a microservices architecture, which I am well-versed in and can readily implement into projects. I am also proficient with Docker and have experience working with both relational databases like Postgresql and non-relational databases like MongoDB.
I actively utilize Rabbit MQ and Unit testing in every project. If you believe I am a suitable candidate, I would be delighted to further discuss the opportunity.
Thank you.
