A facilities management SaaS company was stuck on a legacy PHP application. No mobile support. Feature development had become painfully slow. Years of technical debt made every change risky.
Problem
The architecture could no longer support the features customers needed. Adding mobile capability was practically impossible on the existing codebase. Every new feature took weeks because developers first had to work around years of accumulated technical debt.
The company was losing competitive ground. Competitors shipped mobile apps while they were still patching a desktop-only web application.
Previous approaches
They tried incremental improvements. Each one introduced new problems because the underlying architecture was fragile. Even small changes had unpredictable side effects.
They hired more developers. More people on a bad codebase just meant more people working around the same problems. Development velocity did not improve.
They considered a complete rewrite but feared the risk. Rewrites are notorious for going over budget and over time. They were right to be cautious.
Solution
We took a database-first approach. We started with the data model because it held the business logic that mattered. The PHP code was the liability. The data model was the asset.
We rebuilt the application with Flutter for modern cross-platform support. We migrated all data with zero downtime. The new platform launched alongside the old one, and clients transitioned at their own pace.
Outcome
New features were delivered five times faster. Mobile apps launched within months of the rebuild. The team could build features that had been impossible on the old platform. Development became predictable again.
