Ruby on Rails is a sharp tool. That’s why we love it. However, it also means it’s easy to write code that “works today” but becomes hard to maintain over time. We’ve seen codebases where core classes were opened for small reasons and custom methods were added. In some cases, existing methods were overridden.
These and similar practices can make a codebase harder to understand, harder to test, and riskier to change. Rails usually provides cleaner, more idiomatic ways to solve the same problems. A code audit typically takes 2 to 5 days, depending on the size and complexity of the project.
The audit starts with understanding your application’s shape: the domain model, major workflows, and where the team feels friction today. We then review the code for maintainability, readability, and correctness. We look for “surprises” in the system—hidden monkey patches, implicit callbacks, confusing metaprogramming, and behavior that changes based on load order or environment.
We also examine architectural choices that quietly accumulate cost. Overgrown models, tangled service objects, duplicated business rules, and controllers doing too much work are common culprits. We pay special attention to boundaries: where business logic lives, how data flows, and whether the design makes future changes easier or harder.
A good audit isn’t only about style. We flag correctness and safety issues too: inconsistent validations, missing database constraints, unsafe background job patterns, weak error handling, and places where a small bug could become a big incident. If security or performance issues are obvious during the review, we’ll call them out as well—even if the audit is primarily about code quality.
At the end, you get a detailed report with what we found, why it matters, and concrete recommendations. We also prioritize the fixes: quick wins you can apply immediately, medium-term refactors, and longer structural improvements. The goal is to give your team a clear, practical path to a calmer, more maintainable Rails codebase.
