Background

The Rwanda Revenue Authority (RRA) has operated its core tax systems for more than 10 years. These systems which significantly support revenue mobilization currently run on a monolithic architecture. Over time, several limitations have emerged, including performance degradation, integration challenges, and architectural inflexibility. To address these issues, RRA is undertaking a modernization effort to transition the domestic tax system to a modern microservices-based architecture.

This strategic transformation aims to:

Improve system performance and scalability
Enable smoother integration with external systems
Enhance maintainability and flexibility of tax services
Strengthen automation and data accuracy

Design for security, scalability, and performance, incorporating CI/CD practices and containerization (e.g., Docker, Kubernetes).

Implementation Guidance

Lead architectural decision-making for platform selection and technology stack (e.g. Spring Boot, PostgreSQL/MySQL, and Docker Swarm).
Support setup of development, test, and production environments, including infrastructure and monitoring tools.
Establish architectural standards, documentation templates, and service contracts for micro services.

Quality Assurance & Risk Mitigation
