Familiarity with frameworks such as Spring or Hibernate, experience with version control systems like Git, and sometimes certification like Oracle Certified Professional Java Programmer (OCPJP) are commonly required. Effective problem-solving, teamwork, and attention to detail are crucial soft skills in this role. These skills ensure robust, maintainable, and scalable software solutions that meet project requirements and business goals.
