Architect, build and maintain scalable iOS and Android applications using React Native, Expo and TypeScript.
Develop reusable components, navigation and state/data management; deliver responsive, accessible interfaces for phones, tablets and TVs.
Integrate APIs, authentication, secure token storage, push notifications, deep links and offline/error-handling flows.

Problem-Solving:

Diagnose JavaScript and native crashes, device-specific defects and build failures; resolve root causes using logs and monitoring tools.
Profile and optimize startup time, rendering, memory and network usage across supported devices and operating systems.

Technology Stack:

Own Expo development builds, prebuild, config plugins, native SDK integrations and React Native/Expo dependency upgrades.
Manage EAS Build, EAS Submit and EAS Update, Git-based CI/CD, environment configuration, signing credentials and app-store submissions.

Collaboration:

Clarify requirements with product, design, backend and QA teams; estimate work and independently deliver features end to end.
Lead technical discussions and code reviews, mentor developers, document architecture and raise delivery risks and dependencies early.

Quality Assurance:

Write unit, component and integration tests; support automated end-to-end testing and regression testing on real devices.
Maintain coding standards, secure data handling and production observability; own defect resolution and release readiness.
