Modernizing enterprise operations through robust data migration and orchestration
As part of a major BSS/OSS digital transformation, Telia Sweden initiated the migration of its B2B broadband subscriber base to a next-generation service architecture. The target stack includes:
- Ericsson Order Care

Engineered scalable data transformation solutions to cleanse, enrich, and align subscriber records with the target architecture.
- Test Strategy & Execution
Defined and executed comprehensive test plans, including unit, system, integration, and user acceptance testing, to validate data integrity and functional readiness.
