Why rewrites happen
Most rewrites are not caused by growth alone. They are caused by early decisions that assume the system will stay simple forever.
Three decisions that matter early
- Keep domain logic isolated from framework glue.
- Define stable interfaces before adding feature volume.
- Treat observability as required infrastructure.
Scale path
Start with modular boundaries and explicit contracts. Add capacity by extending modules, not replacing foundations.
Result
You preserve delivery speed while avoiding the financial and operational shock of a full rebuild.
