This skill provides a comprehensive guide for implementing robust testing strategies in Python. It covers essential practices such as unit testing, integration testing, mocking external dependencies, and adopting Test-Driven Development (TDD). Use this when writing complex Python test suites, setting up CI/CD testing infrastructure, or mastering advanced techniques like property-based testing and async code verification.

Expert in designing and implementing advanced Retrieval-Augmented Generation (RAG) pipelines. This role focuses on optimizing the entire information retrieval process—from document chunking and embedding model selection to vector database architectures and hybrid search strategies. The goal is to bridge the gap between raw knowledge documents and accurate LLM understanding, drastically reducing hallucination and enhancing context relevance for enterprise applications.

A specialist guide for building and optimizing modern Rails 7+ web applications. Expertise covers implementing Hotwire (Turbo Frames/Streams) for partial page updates, optimizing Active Record queries (N+1 prevention), configuring real-time communication via Action Cable, managing background tasks with Sidekiq, and ensuring code quality through comprehensive RSpec testing. Ideal for complex, high-performance backend development.

Guides backend engineers through planning, implementing, and validating rate limit middleware across Node.js, Python, Go, and microservice architectures.

A specialist skill for building robust, scalable, and high-performance React applications. Expertise covers modern patterns including React 19, Server Components (RSC), Next.js App Router, and advanced state management (Redux/Zustand). Ideal for implementing complex features, optimizing rendering, and adhering to strict TypeScript/accessibility standards.

This skill provides production-ready architectural patterns for developing mobile applications using React Native and Expo. It covers complex topics including state management, advanced navigation patterns, integrating native modules, and implementing robust offline-first functionalities. Ideal for starting new projects or optimizing existing mobile codebases to ensure scalable and performant results.

Guides selecting and implementing Retell AI architecture blueprints from single webhook servers to event-driven voice pipelines, helping teams match scale, latency budgets, and state management when building or migrating voice agent integrations.

This skill guides the development of robust, high-performance asynchronous Rust applications. It covers essential production patterns using the Tokio runtime, including managing tasks, streams, channels, and proper async error handling. Ideal for implementing concurrent network services or optimizing complex async I/O logic.

This skill provides patterns and implementation templates for managing complex, long-running business processes across multiple independent services. It focuses on implementing the Saga pattern, ensuring data consistency in microservices architectures. It defines clear states, handles step execution, and crucially includes compensation logic to reliably roll back changes when any part of the workflow fails.

This comprehensive guide outlines essential architectural patterns and best practices for developing robust and scalable applications on the Salesforce platform. It details using the @wire decorator for reactive data binding in LWC, implementing bulkified Apex triggers with handler patterns, and leveraging Queueable Apex for asynchronous processing. It also warns developers against common anti-patterns like SOQL/DML inside loops.

This skill involves designing and implementing websites where scrolling is treated as a narrative device, transforming simple navigation into a cinematic, delightful user journey. Expertise covers scroll-driven animations, parallax storytelling, interactive reveals, and sticky sections. It requires a deep understanding of front-end performance optimization, balancing high visual impact with smooth, performant user interaction across devices.

Provides authentication, authorization, encryption, secrets, and hardening patterns for designing secure auth flows, managing tokens, configuring CORS, and implementing best practices around API keys, JWT, OAuth, and rate limiting.
