• Ensure mobile experiences are performant, responsive, accessible, and aligned with the organisation’s design system.
• Integrate mobile applications with backend APIs, microservices, event‑driven systems, and cloud‑native infrastructure.
• Write clean, secure, modular code applying SOLID, DRY, clean architecture, and secure‑by‑default principles.
• Implement advanced mobile patterns including offline support, caching, animations, gestures, native bridges, and deep linking.
• Lead discussions on mobile architecture, patterns, navigation, and platform‑specific differences.

• Partner with UX/UI Designers to bring mobile wireframes, mockups, and prototypes to life with pixel‑perfect accuracy. 
• Provide technical guidance on mobile design feasibility, interaction patterns, and accessibility. 
• Advocate for a mobile‑first, user‑centred approach in all design and development decisions. 

• Define and implement mobile testing strategies including unit, integration, component, and E2E testing (e.g., Jest, React Native Testing Library, Detox/Appium). 
• Promote and support CI/CD automation for mobile builds, releases, and OTA updates (e.g., App Center, CodePush, Fastlane). 
• Lead code reviews to enforce standards, maintainability, and quality consistency across the mobile codebase. 
• Diagnose and resolve performance issues across devices, platforms, OS versions, and environments.
