The "2-in-1" Cross-Platform Strategy
Instead of building and maintaining four separate native apps (iOS Client, Android Client, iOS Cleaner, Android Cleaner), we utilized Flutter. This allowed us to deploy a single codebase across both platforms, significantly reducing development time and maintenance costs.
We took this a step further by engineering a "2-in-1" app architecture. Both the client and cleaner interfaces live within the same application, unlocking the appropriate interface based on the user's role. This dramatically simplified the release process and ensured feature parity across the entire user base.
Backend Reliability & Testing
Trust is the currency of any marketplace. To ensure the system never fails a booking, we built the backend on Laravel, reinforced by an extensive suite of automated test cases.
// Why Testing Matters
Automated testing isn't just for developers. For the business, it means we can deploy new features or fix bugs without the fear of breaking existing functionality. It is the safety net that allows for rapid innovation.
Observability & Real-Time Interaction
We implemented a real-time WebSocket engine for instant chat between clients and cleaners, and utilized Redis for high-speed caching. To keep the system healthy, we deployed advanced monitoring tools that give us visibility into every job, queue, and potential error before it impacts a user.
