Fintech Case Study

How we reduced technical debt for a Fintech scale-up using AI agents

Deployed AI-augmented engineering squads to systematically identify, refactor, and document legacy code, reducing technical debt by 40% in just 3 months while maintaining feature velocity.

The Challenge

The client, a rapidly growing fintech scale-up, was bogged down by accumulating technical debt. Feature delivery had slowed by 50% due to fragile legacy code, lack of documentation, and brittle test coverage. They needed a way to pay down debt without pausing product development.

Our Solution

RSVR deployed an AI-augmented squad specialized in modernization. We used proprietary AI agents to map the codebase, generate missing unit tests, and propose safe refactoring paths. Our senior engineers reviewed and merged these changes, ensuring safety and compliance throughout the process.
