Mazda Austria GmbH
Recommendation Letter
My name is Mario Bruckschwaiger, and I am a Software Architect at Mazda Austria GmbH. During 11.09.2023 – 31.09.2024 I had an opportunity to work closely with Marko Korovin who was interning at our company in the position of Java Developer. In this letter I would like to express my assessment of his professional and personal qualities.

Technical Skills:

Marko has demonstrated a good ability to quickly learn new technologies and frameworks.

During the internship, he has been successfully learning and practicing:

Enterprise JavaBeans (EJB): Marko optimized application performance and created functional modules using EJB. For example, during profiling procedures, he created and customized bins to handle caching of security permissions, which reduced requests processing time by half.

Java Persistence API (JPA): During the process of upgrading the mail module and redesigning the email sending system, Marko utilized existing repositories as well as designed new repositories for database access.

Java Server Faces (JSF): Marko created interactive user interfaces using JSF. His work on various modules enhanced the user experience and visual component of the software considerably.

Marko has successfully utilized the following set of technologies and tools to accomplish the mentioned and other numerous tasks: Java 8/17, Jakarta EE, CDI, SQL, Git, Maven, JUnit, Profiler, SOLID, PrimeFaces, CSS, HTML, Jira.

Marko performed tasks at the level of a full-qualified developer, actively working on real projects and solving complex technical problems. He received support from several experienced developers who acted as mentors, and quickly fit into the team. Marko applied what he learned effectively, demonstrating autonomy in completing tasks. His ability to learn from more experienced colleagues while making meaningful contributions to projects was highly valuable.

Self-improvement: Marko showed a remarkable commitment to self-improvement. He actively searched for new knowledge and ways to improve his skills, regularly learning new materials and technologies. This commitment to continuous learning and development allowed him to quickly become a valued member of the team. The willingness to learn and adapt to new challenges was always at a high level.

Conclusion:I am confident that Marko will be a valuable employee in the software development field. His dedication to learning, professional skills and personal qualities make him an excellent candidate for positions related to Java development and enterprise application development.

Evaluation of the trainee:

The development team at the department for Informatics Didactics was pleased to have found in Korovin an employee who was willing to learn.

Mr. Korovin integrated well into the team, completed all tasks to the project team's satisfaction, and contributed his ideas. In the beginning, the flat organizational structure of the institute caused him some difficulties. Still, he quickly learned to communicate with everyone at eye level and to bring his personality into the group.

In summary, as head of the department, I can assure you that Mr. Korovin has solved his tasks very well, and the cooperation was an enrichment for all.
