Build and change Java backend code using Spring/Hibernate/Struts, write SQL and JUnit tests, and take medium-to-high complexity changes through analysis, design, coding, testing, and deployment.
""Hands on all the phases of SDLC – Analysis, Design, Coding, Testing, Deployment.""
Tech stack maturity
Mainstream Modern
Hibernate, Java, Spring, and SQL are established enterprise backend technologies that are widely used in modern production systems, but they are not specifically cloud-native or bleeding-edge.
