• Implement app performance optimizations, including reducing app size, improving load times, and memory management.
• Debug, troubleshoot, and improve application stability.
• Write unit and integration tests using React Native/React Testing Library to ensure app reliability.
• Collaborate with designers, product managers, and backend engineers to deliver seamless user experiences.
• Integrate APIs, third-party SDKs, and state management solutions like Redux, Zustand, Recoil, or Context API.
• Ensure best practices in code architecture, security, and scalability.
• Utilize AI-assisted development tools (e.g., Claude, GitHub Copilot, Codeium, Codex, Cursor) and understand their strengths, limitations, and best practices for maximizing productivity.

Requirements & Tech Stack

Core Technical Skills

• Expert proficiency in React and TypeScript, with a strong understanding of hooks, state management patterns, and TypeScript best practices.
• Understanding of the RN framework and familiarity with native modules.
• Deep expertise in Next.js, including Server-Side Rendering (SSR), Incremental Static Regeneration (ISR), API routes, middleware, optimization strategies, and the new App Router paradigm.
• Good understanding of ES6+, async/await, functional programming patterns, and modern JavaScript practices.
• Proficiency in modern CSS, including Tailwind CSS, CSS modules, CSS-in-JS solutions (Emotion, Styled Components), and responsive design principles.
• Hands-on experience with modern build tools such as Webpack, Vite, ESBuild, or equivalent bundlers, with an understanding of tree-shaking, code splitting, and lazy loading.
• Good foundation in Git and collaborative development workflows.
• Working knowledge of Node.js and backend fundamentals sufficient to understand API design, authentication, and server-side implications.

System Design & Architecture

• Ability to design scalable, maintainable component architectures and design systems.
• Understanding of state management solutions (Redux, Zustand, Context API) and when to use each.
• Knowledge of micro-frontends, module federation, and how to structure large applications.
• Experience with component composition, prop drilling solutions, and reusable library design.
• Understanding of multi-app strategy, Android AAB, Metric config, and Build Pipelines.

Performance & Monitoring

• Experience with app performance optimization, including profiling, crash rate, ANR, cold & hot boot load times, reducing memory usage, and minimizing bundle size.
• Deep understanding of frontend performance metrics (Core Web Vitals, FCP, LCP, CLS, FID) and optimization techniques.
• Knowledge of monitoring, observability, and error tracking solutions (Newrelic, Sentry, DataDog, etc.).
• Understanding of lazy loading, code splitting, image optimization, and caching strategies.

Quality & Best Practices

• Experience in testing frameworks such as Jest, RN / React Testing Library, Vitest, and E2E testing (Maestro, Cypress, Playwright).
• Sound knowledge of design patterns, SOLID principles, and writing clean, maintainable code.
• Understanding of web accessibility (WCAG standards, semantic HTML, ARIA attributes) and experience implementing accessible UIs.
• Proficiency in browser compatibility and cross-browser testing.
• Exposure to code quality tools like ESLint, Prettier, Husky, pre-commit hooks, and automated CI/CD pipelines.

Nice to Have Skills
