Case Study: a multinational financial technology company de-risks legacy modernization with 10Pearls AI-driven engineering

Multinational Financial Technology de-risks legacy modernization with 10Pearls across 40–50 stored procedures

The customer, a multinational financial technology company, faced the significant challenge of modernizing a complex and undocumented legacy codebase for its B2B financial operations platform. With business logic buried in thousands of lines of SQL stored procedures and a lack of reliable tests, traditional modernization approaches carried high risk. 10Pearls was engaged to address this challenge.

10Pearls implemented a de-risked, incremental modernization strategy using AI-assisted analysis and a Strangler Fig migration pattern. This solution combined AI-driven business rule extraction with human validation to create a reliable foundation and a staged roadmap. The result was a successful initial production deployment, paving the way for a full phased rollout that modernized the critical invoice generation system without interrupting ongoing business operations.
