The Challenge

The existing system consisted of 2 million lines of undocumented code, spread across multiple languages and frameworks. Manual analysis would have taken years.

The Solution

Deployed a multi-agent system using Claude to analyze the codebase, map dependencies, identify dead code, and generate migration plans. Each agent specialized in a different aspect: code analysis, documentation generation, test creation, and migration execution.
