Product rebuild
Replatform a legacy system onto a modern stack ? without losing the decade of business rules that makes it actually useful. We modernise the foundation while your current product keeps running.
When the platform is holding the business back
The signs are familiar: every release is a long weekend, the framework hasn't been updated in five years, nobody who wrote the core is still on the team, and every new feature takes three times longer than it should. A rebuild isn't a rewrite for the sake of fashion ? it's an investment in the next decade of the product.
We run rebuilds as parallel tracks so there's never a 'big bang' cutover. Traffic moves onto the new platform module by module, and we can roll back any slice on its own.
What we protect
- Business rules (documented, tested, carried over)
- Data integrity (dual-write migration where needed)
- User-facing URLs and integrations
- Your SLAs during the transition
Strangler-fig, not big-bang
Map
We document the existing system at the level a new engineer would need: core domains, data flows, integrations, and the handful of 'nobody knows why' behaviours that are actually critical.
Strangle
New modules are built on the modern stack and placed behind the existing edge. Traffic cuts over per capability, guarded by feature flags and observability.
Decommission
Once each legacy module is dark, we archive it with its last-green test run. No mystery leftovers, no forgotten cron jobs.
