About me
I am a backend developer with over two years of experience developing and maintaining enterprise applications. My stack includes Java, Spring Boot, SQL, REST APIs, Docker, GitLab CI/CD, JUnit, and Mockito. I build APIs, system integrations, data-processing services, automated workflows, and solutions for data export and application migration. My work also covers logging and analysis pipelines, authentication, testing, debugging, and performance optimisation. I use AI-assisted tools such as Claude Code where they improve productivity. I am pursuing a Master's degree in Applied Computer Science.
