Code Refactoring & System Stabilisation
Targeted refactoring of existing codebases to reduce technical debt, improve stability, and make ongoing development safer — without stopping production or disrupting business operations.

€5,000 – €20,000
Service Overview
This service focuses on improving the internal quality of your existing system while keeping it fully operational. We refactor production code incrementally, addressing the most risky and costly areas first.
The goal is not cosmetic cleanup, but real stabilisation: fewer regressions, safer releases, and a codebase your team can confidently work with.
How This Service Works
Overview
This service delivers controlled, incremental refactoring of live production systems. We focus on high-impact areas that reduce technical risk, improve maintainability, and stabilise system behaviour — without rewriting the system or disrupting ongoing work.
This service is designed for teams that:
- operate a live system with growing technical debt
- experience frequent bugs or regressions
- struggle to make changes safely
- want to stabilise the codebase before scaling further
After the refactoring work, you gain:
- cleaner, more maintainable code
- reduced technical debt in critical areas
- improved system stability
- safer and more predictable releases
- a foundation for future improvements
All refactoring is delivered incrementally.
Changes are introduced in small, controlled steps, supported by testing and monitoring.
Production systems remain stable, and business operations continue without interruption.
After stabilisation, you can:
- continue refactoring additional areas
- proceed with performance or architectural improvements
- onboard new developers more easily
- maintain the system with lower long-term cost
Common Challenges Before Refactoring
Teams often come to us with issues such as:
- fragile code where small changes cause unexpected failures
- high regression rate after releases
- unclear responsibilities and tangled dependencies
- growing maintenance effort and slowed development
- fear of touching legacy or critical components
What Changes After Refactoring
After refactoring, teams experience:
- improved code readability and structure
- fewer production incidents and regressions
- safer, more predictable deployments
- increased developer confidence and velocity
- reduced long-term maintenance effort
How the Refactoring Process Works
Our refactoring process is structured and production-safe.
1. Target area selection
Identify the most risky or costly parts of the codebase.
2. Refactoring strategy
Define safe refactoring steps and supporting tests.
3. Incremental implementation
Apply changes in small, controlled iterations.
4. Validation and stabilisation
Verify system behaviour through testing and monitoring.
Engagement Model & Pricing Notes
This is not a fixed-scope product. Pricing depends on:
- system size and complexity
- number of components involved
- current code quality and test coverage
Typical engagements fall within the price range shown above.
