PRODUCT ENGINEERING / SYSTEM NODEMobile Development

Cross-platform mobile apps that do not feel cross-platform.

We build React Native applications using platform-appropriate components, meeting App Store and Play Store standards at a quality users will not notice is not native.

WHAT WE BUILD

Mobile Development, engineered as an operating system.

Scope follows the real workflow, environment, failure modes, and ownership model rather than a fixed vendor package.

01

React Native App Build

Full-featured iOS and Android applications from design to App Store and Play Store submission — with production-quality code.

  • iOS & Android
  • App Store submission
  • Production code quality
02

Expo Managed Workflow

OTA update infrastructure, push notifications, and native module integration using the Expo ecosystem.

  • EAS Build
  • OTA updates
  • Push notifications
03

Offline Functionality

Local storage, sync queues, and conflict resolution for applications that must function without reliable connectivity.

  • MMKV / WatermelonDB
  • Sync queue
  • Conflict resolution
04

Performance Optimisation

List virtualisation, animation optimisation, and bundle splitting to maintain smooth interactions on the full device range.

  • FlashList virtualisation
  • Reanimated animations
  • Bundle splitting
05

CI/CD for Mobile

Automated build, test, and distribution pipelines using EAS Build and GitHub Actions — TestFlight and internal track delivery.

  • EAS Build pipelines
  • TestFlight automation
  • Play internal track
DELIVERY SEQUENCE

From unknowns to production evidence.

01

Technical Scoping

Review platform requirements, offline needs, native module integrations, and store submission requirements before any code is written.

Requirements Scope Doc
02

Navigation & Auth

Set up navigation structure, authentication flows, and the API integration layer before building any screens.

Scope Doc App Shell
03

Core Screens

Build core screens iteratively — delivered to TestFlight and Play Store internal track for real-device testing at each milestone.

04

Performance Pass

List virtualisation, animation optimisation, and bundle splitting to maintain smooth interactions across the target device range.

Core Build Optimised Build
05

Accessibility

VoiceOver and TalkBack testing, touch target sizing, and colour contrast across both platforms.

TECHNICAL FAQ

Questions worth resolving before delivery.

01Why React Native instead of native Swift/Kotlin?+

For most business applications, React Native delivers equivalent user experience at significantly lower cost — one codebase instead of two. For highly performance-critical or hardware-intensive use cases, we will tell you if native is the better choice.

02Can you manage App Store submission?+

Yes. We handle the full submission including screenshots, metadata, privacy manifest (iOS), and compliance requirements. Store review timing is controlled by Apple and Google and can vary by submission and account state.

03How do OTA updates work?+

EAS Update lets you ship JavaScript changes without going through store review. Native code changes still require a full store release. We set up the update infrastructure as part of the initial build.

04Do you test on real devices?+

Yes. TestFlight and Play Store internal track are set up early so every milestone is tested on real hardware, not just simulators.
