Legacy Re-engineering
Re-architect aging code without the rewrite risk — behavior preserved, structure restored.
Legacy Re-engineering that earns its place in production
Some systems don't need new infrastructure — they need their internals rebuilt: tangled modules, no tests, ten years of patches on patches. Re-engineering restores structure while preserving behavior, so the system your business depends on becomes one your engineers can change.
The discipline is behavior preservation: we pin down what the system actually does with characterization tests, then restructure underneath that safety net — untangling modules, isolating the database, extracting services where it genuinely pays. Every step is verifiable; nothing is 'trust us'.
Key capabilities
Characterization testing
Pin current behavior before changing anything.
Refactoring at scale
Untangle modules and dependencies systematically.
Data-layer repair
Restore integrity and sanity to grown-wild schemas.
Selective extraction
Pull out services only where the seams justify it.
Where it delivers
Un-freezable system
Make a change-averse codebase safe to work on again.
Pre-acquisition cleanup
Turn technical debt into a system diligence can respect.
Team velocity rescue
Stop a codebase from consuming your best engineers' morale.
Frequently asked
Modernization moves systems to new platforms; re-engineering rebuilds the internals where they run. They often combine, but re-engineering is about code structure, not infrastructure.
