Description:

Senior Full-Stack Developer (Java & React) with 10+ years of experience building scalable web applications and modernizing legacy systems. Specialized in transitioning monolithic applications into modular microservices using Java and Spring Boot, alongside intuitive user interfaces with React, JavaScript, and Bootstrap. Strong background in REST APIs, relational database optimization (Oracle), CI/CD pipelines, and converting core business requirements into reliable technical solutions.

Senior Full-Stack Developer responsible for the hands-on development, refactoring, and full-lifecycle support of enterprise web applications. This role balances day-to-day feature development with system modernization—decoupling legacy architectures into clean, modular, cloud-ready services. The developer works across the full software stack to deliver performant solutions, optimize existing database structures, and enforce engineering best practices through automated testing and clean CI/CD deployment workflows.

Key Responsibilities:

• Application Modernization & Development:
  Refactor legacy Java applications into modular Spring Boot microservices while building responsive front-end components using React and Bootstrap.
• API & Database Engineering:
  Design secure RESTful APIs and execute database schema changes and performance tuning within relational databases (Oracle preferred).
• Requirements & Design:
  Convert complex business needs into clean, maintainable technical implementations while following departmental standards.
• Testing & Quality Control:
  Execute thorough developer-level testing using JUnit, Mockito, and React Testing Library to maintain system reliability.
• Deployment & Ongoing Maintenance:
  Manage application builds, deploy software through CI/CD pipelines, and provide post-launch operational support.
