This comprehensive guide provides patterns for building high-performance, non-blocking applications in Python. It covers using asyncio, async/await, and advanced concurrency techniques to efficiently manage I/O-bound workloads. Ideal for developing high-concurrency web APIs, real-time systems (WebSockets), and performing massive concurrent network requests.

This skill defines the mandatory conventions and architectural guidelines for building robust, cross-platform applications using Avalonia UI and the Zafiro toolkit. It emphasizes functional-reactive programming, strict MVVM adherence, and safe error handling (using Result types) to ensure high maintainability and predictability across all development features and core systems.

Azure Functions is a powerful serverless compute service that allows developers to run event-driven workflows without managing underlying infrastructure. This guide details modern development patterns for .NET, Node.js, and Python, covering best practices like isolated workers, asynchronous programming (async/await), and recommended patterns (e.g., IHttpClientFactory). It also warns against common anti-patterns to ensure robust and scalable cloud solutions.

Master defensive programming techniques for Bash scripts to ensure production-grade reliability. This guide covers advanced error handling, safety best practices, and input validation, making it essential for building fault-tolerant automation, CI/CD pipelines, and system administration utilities that must handle complex edge cases.

A practical, jargon-free guide to fp-ts functional programming - the 80/20 approach that gets results without the academic overhead. Use when writing TypeScript with fp-ts library.

Practical patterns for using fp-ts with React - hooks, state, forms, data fetching. Use when building React apps with functional programming patterns. Works with React 18/19, Next.js 14/15.

This skill provides a comprehensive set of cross-language patterns and best practices for achieving memory-safe systems programming. It covers fundamental concepts such as RAII, ownership models, smart pointers, and robust resource management. Use this guide when writing low-level or systems code, managing critical resources (files, sockets, memory), or debugging complex memory issues to prevent use-after-free errors and memory leaks.

This comprehensive guide covers mastering modern JavaScript features (ES6+), advanced functional programming patterns, and industry best practices. It provides guidance on refactoring legacy code, optimizing performance, managing asynchronous operations, and building highly maintainable, scalable web applications.

Provides idiomatic Ruby and Rails guidance, covering metaprogramming, gem creation, testing pipelines, and performance tuning for clean, maintainable applications.

Expert in writing, reviewing, and debugging idiomatic Rust code. This skill covers deep systems programming concepts, including mastering ownership, lifetimes, and borrowing patterns for guaranteed memory safety. Specializes in building high-performance, concurrent async applications using Tokio, and designing robust APIs using advanced trait hierarchies. Ideal for projects requiring zero-cost abstractions and maximum reliability.

Expert guidance for building Rust 1.75+ services with async Tokio stacks, advanced type system usage, memory-safe systems programming, and production-grade testing and optimization workflows.
