Frontend & Backend Rebuilds

Replace the layer holding the product back without rebuilding everything else.

Sometimes incremental refactoring stops being economical. The frontend may be impossible to extend, the backend may be built on an unsupported framework, or years of workarounds may have made one layer more expensive to maintain than to replace.

That still does not mean the entire product needs a rewrite.

We isolate the layer causing the constraint, define the interfaces it needs to preserve, and rebuild it against the existing system so the transition can happen in controlled stages.

What this includes

  • /Existing frontend or backend assessment
  • /Replacement architecture and transition plan
  • /API and compatibility layer design
  • /Modern frontend or backend implementation
  • /Data and integration migration where required
  • /Staged rollout, testing, and controlled cutover

When teams call us

  • /The frontend prevents meaningful UX improvements
  • /The backend framework is no longer supported
  • /Feature development has become slower than rebuilding the affected layer
  • /Testing or deployment is too fragile
  • /The product needs a new frontend without replacing the backend
  • /The backend needs replacing while apps and integrations continue working

Common questions

How do you decide between refactoring and rebuilding?+

We compare the cost and risk of improving the existing layer against replacing it. A rebuild only makes sense when it gives a clearly better long-term path.

Can you rebuild the frontend without changing the backend?+

Yes. We can preserve existing APIs or introduce an intermediary layer so the frontend can change independently.

Can you replace the backend without breaking existing clients?+

Yes. Compatibility can be maintained through APIs, adapters, versioning, and staged migration while consumers transition to the new backend.

Do old and new versions run at the same time?+

Often, yes. Parallel operation and gradual traffic migration are useful ways to verify the replacement before retiring the old implementation.
