Application re-engineering fixes architecture ceilings - tangled domains, untestable cores, Friday deploys - by rebuilding the same business capability with clear boundaries. Symbiosis AI pins behavior with characterization tests first, then re-architects incrementally so you exit deploy-fear without a greenfield fantasy.
- Domain-driven decomposition of tangled monoliths
- Characterization test harnesses that pin current behavior before change
- Incremental re-architecture: modular monolith or services, chosen per team scale
- CI/CD introduction with zero-downtime deploy patterns
