Este proyecto es un recurso educativo integral y una guía de estudio centrada en la arquitectura de sistemas distribuidos y el diseño de infraestructura backend. Proporciona un plan de estudios estructurado para dominar los principios de escalabilidad, confiabilidad y rendimiento necesarios para diseñar sistemas de software complejos. El repositorio se distingue por ofrecer un enfoque metódico para la preparación de entrevistas técnicas, incorporando patrones de diseño, compensaciones arquitectónicas y herramientas de repetición espaciada para ayudar a los usuarios a retener conceptos complejos. Enfatiza el análisis basado en restricciones, enseñando a los usuarios cómo evaluar requisitos competitivos como latencia, consistencia y disponibilidad al redactar diseños arquitectónicos. El contenido cubre un amplio espectro de capacidades de diseño de sistemas, incluyendo estrategias para el escalado de bases de datos, gestión de tráfico y optimización de infraestructura. Detalla técnicas para el escalado horizontal, almacenamiento en caché multicapa, comunicación asíncrona y descubrimiento de servicios, al tiempo que proporciona marcos para realizar estimaciones de recursos y planificación de capacidad. La documentación está organizada como una guía de estudio, ofreciendo un camino sistemático a través de los fundamentos de la ingeniería backend y el diseño de sistemas a gran escala.
Implements strategies for ranking and prioritizing URLs to optimize web crawling efficiency.
Crawl4AI is an AI-powered web crawling and data extraction engine designed to transform complex web content into structured formats. It functions as a headless browser orchestrator, enabling the navigation of dynamic websites, the execution of custom scripts, and the capture of visual assets like screenshots and PDFs. By integrating language models directly into the extraction workflow, the system converts raw HTML into clean, structured data or Markdown files optimized for downstream ingestion. The platform distinguishes itself through a distributed, self-hosted infrastructure that manages l
Coordinates high-volume data gathering through asynchronous job queues and self-hosted infrastructure to ensure scalable and reliable crawling operations.
Scrapy is a comprehensive framework designed for automated web data extraction and large-scale crawling. It operates on an asynchronous, event-driven engine that manages non-blocking network requests and data processing tasks, allowing for the efficient retrieval of structured information from web documents using path-based selectors. The system distinguishes itself through a highly modular architecture that supports complex data collection workflows. Users can implement custom middleware and signal handlers to intercept and modify request flows, while a priority-based scheduler manages concu
Coordinates high-volume, asynchronous crawling operations to ensure reliability during long-running data collection tasks.
Crawlee is a web scraping framework designed for building scalable, reliable, and distributed data extraction pipelines. It provides a unified interface for managing headless browser automation and lightweight HTTP requests, allowing developers to handle complex web navigation, dynamic content rendering, and large-scale data collection within a single, modular architecture. The project distinguishes itself through its resource-aware concurrency controller, which dynamically scales task execution based on real-time CPU and memory usage to prevent host machine exhaustion. It also features a rob
Persists crawl progress to allow resuming interrupted jobs from the last processed state.
This project is a comprehensive educational guide and framework for building web scrapers using Python. It provides a course-based approach to data extraction, combining a Python crawler framework with tutorials on web reverse engineering and network traffic analysis. The project distinguishes itself by covering advanced extraction challenges, including the decryption of obfuscated JavaScript and the bypass of anti-scraping measures. It specifically addresses mobile application scraping through the simulation of user interactions and the interception of network traffic. The capability surfac
Implements scalable architectures for managing high-volume, asynchronous web crawling across multiple nodes.
PySpider is a Python web crawling framework designed for automated data extraction. It provides a pipeline for periodically fetching web content, processing HTML, and persisting scraped information into database backends. The system features a web-based management interface for editing scraping scripts, monitoring task progress, and reviewing collected data. It includes a headless browser JavaScript renderer to capture rendered HTML from dynamic web pages and a distributed architecture that uses message queues to scale crawling workloads across multiple nodes. The framework also covers task
Provides a framework for high-volume, asynchronous web crawling across multiple nodes using message queues.
This project is a comprehensive knowledge base and study resource designed for mastering technical interviews. It provides structured guides, roadmaps, and curricula focused on data structures, algorithms, system design, and frontend engineering to help candidates prepare for software engineering screenings. The repository distinguishes itself by offering a holistic approach to professional advancement. Beyond technical drills, it includes a career development handbook covering resume optimization, salary benchmarking, and strategic negotiation coaching. It also provides detailed methodologie
