Hi, I'm Mihhail 👋

I'm a Software Development student based in Tallinn, Estonia, focused on Java Backend Development.

I build backend services with Java, Spring Boot, REST APIs, PostgreSQL and Docker.
My main interests are clean API design, reliable data handling, validation, testing, and backend architecture.

Currently looking for a Java Backend Internship or Junior Backend Developer opportunity.
