Migration & Refactoring

Legacy code doesn't mean legacy business

Zero-downtime migrations. Incremental improvement. Your customers never notice, your developers stop crying.

The Problem

The original developer left. The code is spaghetti. Every new feature takes 3x longer than it should. But you can't just stop and rewrite — customers depend on it, and the business can't pause.

The Solution

  • Strangler pattern migrations — new features in new architecture, gradually migrate the rest
  • Zero customer disruption — business continues while we rebuild under the hood
  • Incremental improvement — see progress weekly, not after 6 months of rewrite
  • Knowledge transfer — your team learns the new patterns as we go
