Key Takeaways

  • Define boundaries between product logic and delivery plumbing
  • Adopt typed contracts early to reduce integration churn
  • Design for replaceability, not premature scale

Protect Core Product Logic

MVP teams often mix feature code with framework-specific wiring, which slows change velocity later. Keep domain decisions separate from transport and UI concerns where possible.

Even lightweight boundaries reduce rewrite pressure when your product starts changing weekly.

Type Safety Pays Off Early

Typed request and response contracts reduce hidden breakage between frontend and backend teams. This is especially valuable when roles overlap and velocity is high.

Strong contracts also make onboarding faster as your team grows.

Optimize for Evolution

The goal in MVP is not perfect architecture. It is architecture that survives change. Choose patterns that keep refactoring cheap and failures obvious.

Simple module boundaries, shared validation, and clear deployment flow usually outperform complex abstractions.
