Expo & bare React Native
Greenfield apps on Expo for speed, or bare / prebuild workflows when custom native SDKs are non-negotiable. We document the choice so upgrades stay predictable.
Cross-platform with React
One codebase.
Two native apps.
Zupitrix designs and ships React Native products that feel native on iOS and Android — shared TypeScript business logic, platform-aware UI, Hermes performance, and native modules where the OS matters. You get dual-store velocity without a lowest-common-denominator experience.

Architecture
From JavaScript to native — without losing either side
Zupitrix treats the bridge as a product surface: typed contracts, predictable modules, and platform QA so shared code never becomes lowest-common-denominator UI.
01
React + TypeScript
Screens, state, API clients, design tokens
02
Bridge / JSI
Typed contracts into native modules
03
iOS native
Swift modules, Keychain, APNs, StoreKit
04
Android native
Kotlin modules, Keystore, FCM, Play Billing
What we build
React Native services, end to end
02
Native modules & bridges
Camera, Bluetooth, payments, biometrics, and OEM SDKs wired through typed native modules — with clear ownership of the Swift and Kotlin sides.
03
Performance-first UI
FlatLists, Reanimated gestures, memoized trees, and Hermes — profiled on mid-range devices so launch markets do not only look good on flagships.
04
CI, OTA & store release
EAS or custom pipelines, OTA hotfixes where policy allows, dual-store submission, crash monitoring, and a backlog ready for V1.1.
Stack & tooling
Technologies Zupitrix uses for React Native
Real brand icons for the stack that powers shared UI, native bridges, quality gates, and dual-store release.
Framework
React Native
Cross-platform UI with the New Architecture path and Hermes runtime.
Language
TypeScript
Typed screens, hooks, and native module contracts across the codebase.
Toolchain
Expo
EAS builds, OTA updates, and faster store pipelines when the roadmap fits.
State
Redux
Predictable global state for carts, sessions, and multi-step flows.
Backend
Firebase
Auth, push, analytics, and remote config wired into release trains.
API
GraphQL
Efficient mobile queries with typed clients and cache policies.
Quality
Jest
Unit and component tests guarding regressions before device QA.
Release
Fastlane
Signing, screenshots, and store upload automation for both platforms.
Zupitrix role
Your React Native product partner — not just ticket takers
Zupitrix owns the cross-platform architecture, native bridge strategy, delivery cadence, and store launch. We sit with your product and design leads so trade-offs stay visible — Expo vs bare, shared UI vs platform polish, OTA vs binary releases.
- Architecture decision records for RN, Expo, and native modules
- Shared design tokens with iOS / Android UX variants
- CI/CD, device QA matrix, and dual-store submission
- Post-launch crash triage, OS upgrades, and feature sprints
Why Zupitrix
Cross-platform without cutting corners
Native where it counts
We do not fake hard OS features in JS. Biometrics, payments, and sensors go through proper modules with typed boundaries.
One team, two stores
Shared product ownership with platform QA — fewer handoffs than separate iOS and Android squads, without watering down UX.
Upgrade-safe architecture
New Architecture readiness, dependency hygiene, and clear module boundaries so the app stays maintainable for years.
Outcomes
React Native in the wild
Consumer marketplace
React Native storefront with shared cart logic, native payment sheets, and merchandising rails tuned for one-handed browsing.
Learning & field ops
Offline-first RN client with media capture, background sync, and role-based flows for on-site and remote teams.
Delivery
How Zupitrix ships React Native apps
01
Product & stack fit
Validate RN vs native, Expo vs bare, and must-have device APIs against timeline and team skills.
02
Design system
Shared tokens with iOS and Android variants for navigation, controls, and motion.
03
Build & integrate
Feature sprints, API contracts, analytics, push, and offline paths with weekly device demos.
04
QA on devices
Flagship and mid-range matrix, upgrade paths, accessibility, and store checklist review.
05
Launch & iterate
Store review, OTA hotfixes, crash triage, and a measured V1.1 backlog.
Delivery rhythm
Weekly device demos, shared backlog, and store-ready binaries — with OTA for JS-only fixes after launch when policy allows.
- Shared TypeScript backlog across iOS and Android
- Device matrix QA before every store cut
- Crash monitoring wired into the first release
