• Build scalable UI applications using React (web) and React Native (mobile).
• Develop responsive web apps and cross-platform mobile applications.
• Create reusable, maintainable UI components and design systems.
• Ensure cross-browser and cross-platform compatibility.

Performance and Optimisation:

• Optimise: Backend (query performance, indexing, memory usage) and Frontend (render cycles, bundle size, API efficiency).
• Monitor system performance and user interaction metrics.

Architecture and Collaboration:

• Contribute to system architecture and frontend design decisions.
