• Cloud & Database Integration: Deploy and maintain Java-based applications across AWS cloud infrastructure, Linux OS, Apache Tomcat, and Oracle databases.
• Build Pipeline Management: Utilize build and version control tools (Maven, Gradle, Git, Jenkins, Eclipse) to support continuous integration and deployment in a secure environment.

Minimum Qualifications

• Core Java: OOP concepts, multithreading, and JVM memory management
• Spring and Spring Data JPA
