Feature Evolution

• Guarantee that new implementations do not introduce regressions into existing workflows.

3. Legacy Modernization

• Identify opportunities to refactor and modernize older codebases to improve maintainability, scalability, and security.

• Minimum 2–3 years of professional experience in Java backend development.

• Strong proficiency in Java (Spring Boot, Spring MVC, Hibernate / JPA).

• Solid experience with relational databases and SQL (MySQL, PostgreSQL, or Oracle).

• Practical experience with ReactJS and/or NodeJS for frontend/full-stack integration.

• Experience with RESTful API design, implementation, and integration.

• Ability to conduct root cause analysis and deliver durable solutions for complex production issues.

• Familiarity with version control systems (Git) and CI/CD pipelines.
