QTRAX — Enterprise Music Web Application

Situation

The project involved an existing enterprise application where development work was affected by:

• Ambiguous or incomplete requirements.
• Technical blockers during implementation.
• Existing modules requiring enhancement and bug fixes.
• Integration requirements with third-party music APIs.
• Coordination challenges with a technical leader working in a different time zone.
• The need to maintain development momentum despite asynchronous communication.

Task

Develop and maintain QTRAX, a music-focused enterprise web application supporting music-related operational workflows and integration with third-party music services. The project focused on backend development, application-module enhancement, third-party API integration, bug resolution, and continuous improvement of the existing Java-based application.

Solution

Contributed to the QTRAX platform as a backend-focused Software Engineer using Java, Spring MVC, and Hibernate. The implementation focused on:

• Backend module development.
• Spring MVC application development.
• Hibernate-based database access.
• Third-party music API integration.
• Existing module enhancement.
• Bug fixing.
• Requirements analysis.
• Clean and maintainable code delivery.
• Proactive technical communication with the remote technical leader.
