Decomposing a monolithic telecom billing system (e.g., legacy Oracle BRM or custom C/C++ solutions) is a high-stakes engineering project. Manual analysis and refactoring of rating, charging, and invoicing logic is slow, error-prone, and jeopardizes revenue assurance. A custom automation workflow directly targets this bottleneck, parsing millions of lines of undocumented code to map business rules, identify bounded contexts for microservices, and generate validated target code. This reduces migration planning from years to months and de-risks the core financial engine of the operator.
