  • 15+ years of hands-on Java development experience.
  • Strong understanding of Java SE and EE, including Swing, Servlets, JSP, JDBC, and multithreading.
  • Experience with newer frameworks like Spring, Spring Boot, and RESTful API development.
  • Proficiency in relational databases (MySQL, PostgreSQL, or Oracle) including SQL optimization and stored procedures.
  • Familiarity with build tools (Maven, Gradle) and version control (Git).
  • Solid grasp of object-oriented design principles, design patterns, and software development best practices.
  • Knowledge of front-end integration using HTML, CSS, and JavaScript is a plus.
  • Excellent problem-solving, debugging, and analytical skills.

Preferred Qualifications

  • Experience migrating legacy systems to modern Java platforms.
  • Familiarity with containerization (Docker) and CI/CD pipelines.
  • Exposure to microservices architecture and cloud platforms (AWS, Azure, or GCP).

What We Offer
