Modernize legacy systems without a rewrite
Big-bang rewrites usually fail. The incremental "strangler" approach is slower to start and far safer to finish.
The instinct with a painful legacy system is to throw it away and start over. Most of those projects fail, run over, or quietly get cancelled after a year. There's a safer path.
Why rewrites fail
A full rewrite means you stop delivering value while you rebuild everything you already had, racing a moving target, before you can ship anything. The old system keeps changing, the new one is always "almost done," and risk piles up until someone pulls the plug.
The incremental alternative
Put the legacy app behind a routing layer, then replace one surface at a time. Each piece ships independently, each is measured against the old behaviour, and you can stop or roll back at any point. The system keeps working, and keeps earning, the whole way through.
What it buys you
No big-bang cutover, no frozen feature roadmap, and no single terrifying launch. Just a steady, measurable migration that leaves you with a stack your team can move on again. It's less dramatic, which is exactly the point.
