Context

Critical legacy codebase that was hard to evolve.

Problem

High time to understand the system and risky changes.

What I did

Structured discovery and automation to map legacy behavior.

• Mapped business rules and flows with automated analysis.
• Built a reproducible legacy environment for validation.
• Created a discovery playbook and validation tests.

Result

Faster discovery and safer changes.

Scope & timeline

4-6 weeks.

Before / after

Before: changes took months of discovery. After: faster diagnosis and safer changes.
