Claude Skills by Intense-Visions

> Set up and configure Expo projects with managed workflow, EAS Build, development builds, and config plugins

> Build performant scrollable lists with FlatList, SectionList, and FlashList for large data sets

> Implement touch gestures with React Native Gesture Handler for swipe, pan, pinch, and long press interactions

> Bridge native platform APIs into React Native with Expo Modules API and Turbo Modules

> Implement stack, tab, and drawer navigation in React Native with type-safe routing and deep linking

> Handle network requests, offline support, caching, and connectivity monitoring in React Native

> Optimize React Native app performance with profiling, memoization, lazy loading, and native thread management

> Implement push notifications with Expo Notifications, Firebase Cloud Messaging, and Apple Push Notification Service

> Persist data on mobile with AsyncStorage, SecureStore, MMKV, and SQLite for different use cases

> Test React Native apps with Jest, React Native Testing Library, and Detox for unit, integration, and E2E coverage

> LLM-judgment skill that critiques identifier names — variables, functions, types, and files — for clarity, concreteness, weight, and predictive power. First member of the craft-pipeline initiative. Uses a curated rubric catalog seeded from Martin / Beck / Karlton. Emits 3-axis findings (tier × impact × confidence per ADR 0019).

> Manage environment config with ConfigModule.forRoot, ConfigService, and Joi schema validation

> Define HTTP route handlers with @Controller, method decorators, params, and versioning

> Master NestJS DI container with tokens, useClass/useValue/useFactory providers

> Build event-driven systems with EventEmitter2, CQRS module, CommandBus, and QueryBus

> Handle errors globally with @Catch, ExceptionFilter, and custom exception hierarchies

> Build GraphQL APIs with GraphQLModule, @Resolver, @Query/@Mutation, @ObjectType, and DataLoader

> Protect routes with @UseGuards, CanActivate, JWT guards, and role-based access control

> Transform responses and add cross-cutting behavior with NestInterceptor and CallHandler

> Connect services with ClientsModule, @MessagePattern, @EventPattern, and TCP/Redis transport

> Apply NestMiddleware and functional middleware with consumer.forRoutes binding

> Organize NestJS applications with cohesive feature modules, controlled exports, and composable dynamic configurations

> Validate and transform request data with PipeTransform, ValidationPipe, and custom pipes

> Encapsulate business logic in @Injectable services with repository pattern separation

> Document APIs with @ApiProperty, @ApiOperation, @ApiTags, and DocumentBuilder

> Test NestJS apps with Test.createTestingModule, jest mocks, supertest e2e, and overrideProvider

> Structure Next.js 13+ applications using the App Router's file-system conventions for layouts, nested routes, and route segments

> Implement authentication with session handling, middleware guards, and Auth.js integration

> Control Next.js's four cache layers to balance freshness, performance, and cost

> Fetch server-side data efficiently without waterfalls using async Server Components

> Reduce bundle size, split code strategically, and optimize runtime performance for production

> Manage environment variables, runtime config, and server-only module boundaries safely

> Handle runtime errors and missing routes gracefully with error.tsx and not-found.tsx

> Serve optimized, correctly sized images automatically with next/image

> Define SEO metadata, Open Graph tags, and dynamic OG images with the Metadata API

> Run code at the edge before a request completes — redirect, rewrite, or modify responses

> Configure Next.js inside a monorepo with shared packages and Turborepo task orchestration

> Render multiple pages simultaneously in one layout and intercept routes for modal patterns

> Create HTTP endpoints in the App Router using route.ts with typed method exports

> Mutate server-side data directly from components using async functions — no API route required

> Keep data fetching and heavy logic on the server; push interactivity to the client only where needed

> Pre-render pages at build time or on a schedule using SSG, generateStaticParams, and ISR

> Stream server-rendered HTML progressively using Suspense boundaries and loading.tsx
