patterns▌

Modern React component patterns for building scalable, maintainable UI libraries. \n \n Covers five core patterns: props API design with TypeScript, composition, render props, custom hooks for logic separation, and performance optimization with React.memo and useMemo \n Includes compound components, polymorphic components, and context-based state sharing for flexible, reusable architectures \n Enforces single responsibility, accessibility standards (aria-*, role, tabindex), and prohibits prop dr

Battle-tested patterns for creating custom MQL5 indicators with proper display, buffer management, and real-time updates.

Composition patterns for building flexible, maintainable React components. Avoid boolean prop proliferation by using compound components, lifting state, and composing internals. These patterns make codebases easier for both humans and AI agents to work with as they scale.

Comprehensive testing strategies for Python using pytest, fixtures, mocking, and test-driven development. \n \n Covers unit, integration, functional, and performance testing with the AAA pattern (Arrange, Act, Assert) for test structure \n Includes 10 fundamental and advanced patterns: basic tests, fixtures with setup/teardown, parameterization, mocking, exception handling, async testing, monkeypatching, temporary files, custom fixtures, and property-based testing \n Provides test design princip

Comprehensive guide to designing distributed systems with service boundaries, communication patterns, and resilience strategies. \n \n Covers service decomposition by business capability and domain-driven design, with the Strangler Fig pattern for gradual monolith migration \n Includes synchronous (REST, gRPC) and asynchronous (Kafka, message queues) communication patterns with event-driven architecture examples \n Provides Saga pattern implementation for distributed transactions with compensati

JPA/Hibernate patterns for entity design, relationships, query optimization, transactions, and performance tuning in Spring Boot. \n \n Covers entity mapping with auditing, soft deletes, indexing, and enumerated types; includes transaction management with read-only optimization and propagation strategies \n Provides N+1 prevention techniques using lazy loading, JOIN FETCH queries, and DTO projections for lightweight reads \n Demonstrates pagination with Pageable, custom repository methods, and c

Establish design token hierarchies, theming infrastructure, and component architecture for scalable design systems. \n \n Covers three-layer token organization: primitive tokens (raw values), semantic tokens (contextual meaning), and component tokens (specific usage) \n Includes theme switching patterns with CSS custom properties, React context providers, system preference detection, and persistent storage \n Provides component architecture patterns including compound components, polymorphic var

Production-grade C#/.NET patterns for APIs, MCP servers, and enterprise backends with modern async, DI, and data access practices. \n \n Covers clean architecture project structure, dependency injection lifetimes, and configuration with IOptions pattern \n Async/await best practices including parallel execution, ConfigureAwait usage, and ValueTask optimization for hot paths \n Entity Framework Core and Dapper repository patterns with query optimization, multi-mapping, and performance considerati
