When architecture - not language - is the ceiling, we re-engineer: same business capability, new structure. Clear domain boundaries, testability, and an exit from deploy-on-Friday-and-pray.
- 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
