iOS Developer

This iOS Developer is a full-stack engineer with deep iOS expertise who builds cross-platform

mobile applications using React Native while maintaining strong native iOS skills for platform-specific

optimizations. Beyond mobile, this role contributes to backend services (NestJS/Python) that power

mobile features and builds web features when capacity allows. The individual owns the iOS

experience end-to-end: from API integration to App Store deployment, performance optimization,

and platform-specific native module development.

Responsibilities

iOS & React Native Development (Primary Focus)

Build and maintain the iOS mobile application using React Native with TypeScript.

Develop platform-specific native modules (Swift/Objective-C) when React Native

abstractions are insufficient.

Optimize iOS performance memory management, battery optimization, app launch time,

smooth animations.

Manage App Store deployment pipeline builds, code signing, TestFlight, App Store Review

process, phased releases.

Implement iOS-specific features: push notifications (APNs), deep linking, HealthKit

integration, permissions.

Debug iOS-specific issues using Xcode, Instruments, Flipper, and React Native debugging

tools.

Ensure consistent UX between iOS and Android implementations.

Full-Stack Backend Contributions

Build and maintain NestJS API endpoints that power mobile features push notification
