Results for “mobile-performance”

Mobile-first design thinking and decision-making for iOS and Android apps. Touch interaction, performance patterns, platform conventions. Teaches principles, not fixed values. Use when building React Native, Flutter, or native mobile apps.

Improve interface performance across loading speed, rendering, animations, images, and bundle size. Makes experiences faster and smoother.

Runs a headless-Chromium sweep at phone/tablet widths to catch off-screen overflow, tiny touch targets, clipped text, and oversized modals, then reports each offender with a screenshot and a concrete fix.

Improve cache efficiency, latency, and throughput for AMS deployments using the Adobe Dispatcher Apache HTTP Server module and related HTTPD configuration.

Measures application performance first, identifies bottlenecks, and applies targeted fixes for frontend and backend systems.

Trigger: web performance, slow load, bundle size, lazy loading, LCP, CWV optimization, fetch priority. Scope: Frontend optimization, loading speeds, asset minimization. Boundary: Excludes backend database indexing or visual design systems.

Expert agent for React Native mobile development across iOS and Android with native modules, navigation, and platform-specific code

Optimize web performance by applying browser networking, protocol, and rendering principles to reduce latency and improve Core Web Vitals.

Audits and fixes responsive design issues across specified pages or sections, covering breakpoint coverage, layout collapse, touch targets, typography scaling, overflow, and navigation, with mobile-first enforcement for Next.js and Tailwind projects.

Improve interface performance across loading speed, rendering, animations, images, and bundle size. Makes experiences faster and smoother.

Both directions produce working layouts, but very different amounts of CSS.

Develop React Native, Flutter, or native mobile apps with modern architecture patterns. Masters cross-platform development, native integrations, offline sync, and app store optimization. Use PROACTIVELY for mobile features, cross-platform code, or app optimization.

WordPress performance optimization: performance, slow query, N+1 query, Query Monitor, autoload audit, autoload options, object cache, Redis, wp_cache, transient, cache invalidation, Core Web Vitals, LCP, CLS, INP, FID, profiling, Xdebug, microtime, pre_get_posts, database query optimization, TTFB, page load, Vite bundle, lazy loading, critical CSS — benchmark before/after, never optimize blind. Invoke for: slow page load, N+1 query problem, caching strategy, transient API, dequeue unused scripts, performance profiling, Core Web Vitals improvement.

Use this when the team needs to improve latency, throughput, render performance, query speed, worker throughput, or resource usage across frontend, backend, database, or background systems.

Optimiza el rendimiento web midiendo Core Web Vitals, analizando el bundle y aplicando mejoras como lazy loading, code splitting y optimización de imágenes y fuentes.

Mobile development with React Native, Flutter, and native patterns

React Native and Expo best practices for building performant mobile apps. Use when building React Native components, optimizing list performance, implementing animations, or working with native modules. Triggers on tasks involving React Native, Expo, mobile performance, or native platform APIs.

React Native and Expo best practices for building performant mobile apps. Use this skill when building React Native or Expo applications, optimizing list performance with FlashList, implementing animations with Reanimated, configuring native modules, routing with expo-router, managing state in mobile contexts, or working in monorepo setups with Expo. Apply proactively when writing FlatList, useEffect for animations, TouchableOpacity, or setting up navigation — these patterns prevent common mobile performance pitfalls.

Builds, optimizes, and debugs cross-platform mobile applications with React Native and Expo, covering navigation, native modules, list performance, and platform-specific code.

Use when building, optimizing, or debugging cross-platform mobile applications with React Native and Expo. Provides guidance for navigation setup, native module integration, performance optimization, and platform-specific handling for iOS and Android.

Cypress E2E testing framework. Covers commands, assertions, and component testing. Use for end-to-end testing. USE WHEN: user mentions "cypress", "e2e test", "cy.get", "cy.visit", asks about "cypress intercept", "component testing", "cypress commands" DO NOT USE FOR: Unit tests - use `vitest` or `jest`; Multi-tab scenarios - Cypress doesn't support; Native mobile apps - use Appium; Performance testing - use dedicated tools
