Master iOS development with Swift, Android development with Kotlin, React Native, Flutter, and cross-platform mobile technologies.

Apply systematic problem-solving techniques for complexity spirals (simplification cascades), innovation blocks (collision-zone thinking), recurring patterns (meta-pattern recognition), assumption constraints (inversion exercise), scale uncertainty (scale game), and dispatch when stuck. Techniques derived from Microsoft Amplifier project patterns adapted for immediate application. | Dùng khi giải quyết vấn đề, tìm giải pháp, phân tích, tối ưu, thuật toán, bị kẹt.

Firebase Firestore specialist covering NoSQL patterns, real-time sync, offline caching, and Security Rules. Use when building mobile-first apps with offline support, implementing real-time listeners, or configuring Firestore security.

Structured approach to exploratory data analysis with pandas, matplotlib, and seaborn. Use this skill when analyzing new datasets, understanding distributions, or preparing data for modeling.

Find THE single highest-leverage intervention point where minimal effort produces 10x or greater impact through bottleneck removal, amplification, or compounding effects. Use when: (1) asked "where's the leverage point" or "what's the force multiplier" to identify exceptional ROI opportunities, (2) linear approaches produce inadequate results and you need to find the one change that unlocks everything else, (3) repeated effort or duplicated work signals a system-level leverage opportunity rather than individual task optimization, (4) seeking the intervention that creates multiplicative value rather than evaluating which of many items to do first

Implement secure error handling to prevent information leakage and provide appropriate error responses. Use this skill when you need to handle errors in API routes, prevent stack trace exposure, implement environment-aware error messages, or use the error handler utilities. Triggers include "error handling", "handle errors", "error messages", "information leakage", "stack trace", "handleApiError", "production errors", "error responses".

Generates React Native components with platform-specific code, TypeScript support, and mobile-first patterns. Use when user asks to "create React Native component", "generate RN component", "scaffold mobile component", or "create cross-platform component".

Convert JSON ABI files to TypeScript const exports with proper typing. Use when working with smart contract ABIs, converting JSON to TypeScript, generating typed contract interfaces, or adding new contract ABIs to the SDK.

Creates sophisticated HBR-style editorial illustrations for any content using AI understanding and visual analysis. Use when creating conceptual illustrations, analyzing generated images, or compositing logos. Works with any brand configuration. AI-native approach - Claude reasons about content rather than using rigid templates.
