Cross-Platform Mobile App Development

A mobile app that works on both Android and iOS without maintaining two separate codebases is not a shortcut — it is the right architecture for most business applications. I build mobile apps using Flutter and Dart, backed by Laravel REST APIs, for clients who need a reliable application deployed across the Kenyan Android-dominant market and the iOS segment that matters for premium services.

Flutter and Why It Makes Sense for Kenyan Markets

Flutter compiles to native ARM code on both Android and iOS, which means it performs like a native app rather than a web view wrapped in a shell. In a market where entry-level Android devices are common, this matters. The UI renders at 60fps on modest hardware, and the app does not require a browser to function.

A single codebase covering both platforms means half the development time compared to separate native apps, and half the maintenance work when you need to push updates. For most business applications — field agent tools, customer-facing service apps, mobile banking light clients, and internal operations tools — Flutter is the correct technical choice.

Backend: Laravel REST API

Every Flutter app I build is backed by a Laravel REST API that handles authentication, data storage, business logic, and integrations. The API is built with the same standards as a web application: versioned endpoints, proper HTTP status codes, authentication via Laravel Sanctum, and rate limiting. This means your mobile app and your web application can share the same backend without duplicating business logic.

Payments: M-Pesa and Card

I integrate M-Pesa STK Push directly from the mobile application, allowing users to pay without leaving the app. The payment flow handles the full lifecycle: initiating the Daraja request, displaying a waiting screen while the Safaricom prompt appears on the user's phone, receiving the callback via the Laravel API, and updating the app in real time. Card payments via Stripe or Paystack are also supported for users paying by Visa or Mastercard.

Offline Capability

In areas with unreliable mobile data, a fully online-only app breaks at the worst moment. For field agent applications — loan officers, delivery drivers, community health workers, agricultural extension officers — offline-first data models can be built using Flutter's local database (Hive or SQLite) that sync with the Laravel backend when connectivity is restored. Conflict resolution is handled server-side with clear rules rather than silent overwrites.

Push Notifications and Real-Time Updates

Firebase Cloud Messaging (FCM) for push notifications: order status updates, payment confirmations, appointment reminders, system alerts. For applications requiring real-time updates — live delivery tracking, live chat, auction bidding — I implement WebSocket connections or server-sent events from the Laravel API.

App Store Deployment and Ongoing Support

I handle the Google Play and Apple App Store submission process, including setting up developer accounts if needed, managing signing certificates, and navigating the review process. After launch, I provide support for OS update compatibility, Safaricom Daraja API changes, and feature additions as your business grows. I have maintained Flutter apps in production and know what breaks when Android or iOS ships a major version update.
