Skill UI

A comprehensive guide for building production-quality Android applications using Jetpack Compose. This skill covers modern architectural patterns (MVVM/MVI), robust state management with StateFlow, optimized UI rendering, type-safe navigation setup, and performance best practices (e.g., recomposition control). Use this skill when developing complex, modern Android user interfaces.

A comprehensive guide detailing best practices for optimizing Angular applications. It covers critical topics like change detection strategies (OnPush, Signals), managing asynchronous data flows (avoiding waterfalls), optimizing bundle size via lazy loading and tree shaking, and improving rendering efficiency with modern features like @defer and trackBy. Use this when building, reviewing, or refactoring complex Angular components for peak performance.

This guide provides a comprehensive roadmap for migrating legacy AngularJS (1.x) applications to modern Angular (2+). It covers essential techniques like component and directive conversion, dependency injection updates, and routing migration. Learn advanced strategies for building hybrid apps and executing safe, incremental upgrades for large-scale enterprise applications.

This comprehensive guide covers modern state management patterns in Angular, including local state using Signals, complex global state handling with NgRx, and remote data synchronization with NgRx Query. It helps developers understand when to use Signals, NgRx, or other solutions for building robust, scalable, and maintainable applications.
