    Brief

    This opportunity involves designing and implementing a transitional architecture for the integration and modernization of the PROCAT (Procurement Catalog) and SAR (System Architecture Review) systems. The project seeks to establish a comprehensive roadmap and technical framework that bridges legacy systems with modern infrastructure, ensuring seamless data migration, system interoperability, and minimal operational disruption during the transition period.

The work requires expertise in enterprise architecture, system integration, legacy system modernization, and change management to facilitate a smooth transition while maintaining system availability and data integrity.
