Presentation: Moving Mountains: Migrating Legacy Code in Weeks instead of Years
Not a pilot. ServiceTitan deployed AI agents to refactor legacy code in weeks instead of years—using assembly-line parallelization and validation loops to eliminate hallucinations.
Why it matters
Demonstrates production-grade AI agent deployment for enterprise engineering workflows. Shows how rigid validation + task decomposition solves the hallucination problem at scale—a replicable pattern for any large-scale code migration.
