Terraforming legacy Rails applications
summary
Shows concrete refactors and tools: Docker + a DIP wrapper for repeatable dev setups, replacing ENV sprawl with named YAML plus Rails credentials, and cutting CI test time by about fourfold using TestProf (batch, profilers, factory fixes and a Factory Linter). Adds runtime guards with Isolator, schema/model checks via database_consistency and database_validations, progressive RuboCop rules (strict + standard), and Git/PR automation with Left Hook and Danger; code and scripts are on GitHub.
