Work Experience

During this onsite internship I focused on rapid, hands-on learning of modern backend and software technologies, gaining practical exposure to Java, Spring Boot, REST API design, and Maven; studying authentication and authorization with Spring Security, Basic Auth and JWT; containerizing services with Docker; using Redis for caching and SLF4J for structured logging; practicing test-driven development, unit testing, and improving code quality with code coverage tools and SonarQube; and familiarizing myself with the ELK stack (Elasticsearch, Logstash, Kibana) and Linux command-line troubleshooting-prioritizing skill acquisition and practical demos over full-scale project ownership.
