Fix what you have
Legacy Application Rescue
Inherited a codebase that nobody wants to touch? A Code Bunny will audit what you have, identify the risk, and get it back into a state you can ship from confidently. We have upgraded Rails apps from version 4 through to current, added test coverage to untested codebases, and resolved CVEs that had been sitting open for years.
- Read-only audit first. Security, dependency health, and coverage gaps in a written report – before any work is agreed.
- Rails and Ruby upgrades. One minor version at a time, from as far back as Rails 4, while the app keeps shipping.
- Coverage without a rewrite. Tests built progressively around the money paths, so refactoring stops being frightening.
- CVE and dependency triage. Years-old advisories resolved – and kept resolved.
- Performance work. Profiling, N+1 elimination, and the slow queries nobody had time to find.
- The missing manual. We document the parts no one ever wrote down.
A codebase you can ship from weekly, instead of one you are afraid to deploy.
