Refactoring and porting across languages
Transformation of existing, often legacy or fragile software into a more readable, maintainable, testable version or one portable to a different stack. AI accelerates code reading, generation of alternatives, patch production. The critical part stays technical: preserving semantics, detecting regressions, building tests, verifying functional equivalence.
Porting is not syntactic translation. It is controlled preservation of behaviour inside a new technical context.
When it fits
When it fits
When a system works but has become painful to maintain. When you must migrate to a more modern language or framework without losing logic accumulated over years. When a twenty-line script has become critical and must become a robust service. When an AI-assisted prototype must become production code.
What I actually do
What I actually do
- Refactoring legacy code to make it testable
- Cross-language migration (e.g., PHP → Python, Java → Go)
- Converting ad-hoc scripts → robust versioned services
- Prototype → maintainable software transformation
- Module separation · API extraction
- Containerization of monolithic applications
- Generating missing regression tests
- Before/after behaviour verification of the transformation
What I deliver
What I deliver
- Transformed code with associated regression tests
- Before/after documentation with behaviour comparison
- Structured diff of transformation decisions
- Module-to-module mapping (in case of porting)
- Test suite sufficient to cover critical behaviour
- Verified functional-equivalence report
Method
Method
Before transformation: building a test suite that documents current behaviour (even when the legacy had none). During: AI proposes, technical judgment decides, each step compares behaviour before/after. After: formal verification of functional equivalence, identification of acceptable and unacceptable drift, consolidation. No blind rewrite: every change is traceable and reversible.
