🏚️AI & Legacy Code
How to use AI to understand, test, and modernize code nobody wants to touch.
What you'll learn
- Use AI to extract architecture and dependencies from undocumented code
- Create AI-generated test harnesses for safe refactoring
- Plan framework or language migrations with AI assistance
- Build a modernization roadmap with priorities and estimates
Who this is for
Developers, tech leads, and architects working with older codebases who want to modernize them with AI assistance.

Syllabus
Understanding Legacy Code with AI
Every developer knows the feeling: you open a repo, no docs, no tests, the original authors long gone. AI helps you understand what the code does — and why.
Safe Refactoring with AI
Refactoring legacy code without tests is like surgery without imaging. AI helps you build a safety net first — then cut.
AI-Generated Tests for Untested Code
Zero test coverage is not a death sentence. AI can generate a meaningful test suite in hours, not weeks.
Migration Patterns with AI Assistance
Framework or language migration is a project everyone dreads. With AI you can eliminate 80% of manual work and dramatically reduce risk.
Documentation Rescue with AI
From zero docs to full coverage in a fraction of the time. AI reads code and writes documentation you would never have time to write yourself.
Modernization Roadmap: Priorities, Estimates, Risks
You cannot modernize everything at once. AI helps you decide what first, what later, and what to leave alone.
