The company is launching a new external, public-facing web application called Reporting Analytics Hub. The solution will be built using microservice architecture, Java, Spring Boot, and Angular, leveraging an internal framework (“fate") developed by Manuel. The application will integrate Power BI reports and connect to the internal data science platform. Users will access reports based on role-based access controls. A similar application already exists and can be used as a scaffold for faster delivery, although several adaptations are needed-including enabling multi-tenancy.

- Ensure compliance with security and governance standards (especially due to customer identifying data).
- Participate in requirement workshops and customer meetings.
- Support architectural decisions and technical solution design.
