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.

Expert proficiency in modern Angular development (v20+). Mastery includes Signals for fine-grained reactivity, Standalone Components for modular architecture, and Zoneless applications for peak performance. Skilled in implementing SSR, Hydration, and adopting the latest reactive patterns to build highly performant, scalable enterprise frontend applications.

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.

Modern Angular UI patterns that coordinate loading spinners, skeletons, error states, empty states, and progressive data display; designed for component builders managing async data, optimistic updates, and graceful degradation.

Master REST and GraphQL API design principles to build intuitive, scalable, and maintainable APIs. This skill guides users through establishing robust design standards, reviewing specifications, and optimizing APIs for various use cases, ensuring longevity and developer delight.

Auto-activating visual content skill that helps you plan and build API flow diagrams, covering best practices, Mermaid-style layouts, production-ready code, and standard validations when the topic is mentioned.

A comprehensive guide to modern API design principles and architectural decision-making. Learn how to select the right pattern (REST, GraphQL, tRPC), implement robust versioning strategies, handle pagination, define standardized response formats, and incorporate essential security measures like authentication and rate limiting. Essential for building scalable and reliable backend services.

A comprehensive guide for developers on building secure and robust APIs across REST, GraphQL, and WebSocket protocols. It covers essential security patterns including robust authentication (JWT, OAuth 2.0), granular authorization (RBAC), input validation to prevent injection attacks (SQLi, XSS), rate limiting, and best practices for data encryption and secure headers. Essential for developers preparing for security audits.

An expert framework for creating realistic API mock services. It simulates real API behavior and contracts, enabling developers to build and test frontend components or integration workflows in parallel, even before the actual backend service is complete. Ideal for testing, demo environments, and validating API contracts.
