Hi, I’m looking for a developer to build a reliable product scraper for Allegro.pl. The scraper should be able to collect product data at scale, including: Product name Price Product URL Images Seller information Availability Category Other relevant product details The solution should be robust, scalable, and minimize the risk of IP bans or request blocking by using appropriate request rates, caching, retries, and other legitimate scraping best practices. Please let me know if you have experience with large-scale web scraping and anti-bot protected websites, and provide examples of similar projects you have completed.

✋ Hi, the main challenge here is keeping extraction reliable at scale while handling changing page structures, rate limits, retries, and partial failures without corrupting the dataset. I’d first identify the cleanest data source available, then build the scraper around controlled concurrency, caching, retry logic, validation, and resumable jobs so long runs remain stable. Do you need scraping from specific categories/search results, or should it crawl the wider Allegro catalog?

ASAP - QA - SPECIALIST I have strong experience building large-scale Python scraping systems that collect structured product data, handle dynamic websites, and remain reliable as page structures and traffic conditions change. I’ve worked with scrapers requiring careful request management, retries, caching, validation, pagination, proxy-aware architecture, and scalable data pipelines. I’ll build the Allegro scraper with a modular architecture for product discovery, extraction, image and seller data, deduplication, storage, retries, rate limiting, and monitoring, while respecting Allegro’s applicable terms and robots/access rules. I’ll optimize the crawler for reliable throughput using caching, controlled concurrency, backoff, session management, and robust parsers so temporary blocks or page changes do not bring the entire pipeline down. The result will be a maintainable scraper that can scale from initial product collections to significantly larger catalogs while producing clean, consistent data ready for your application or database.

Hi, this Allegro scraper needs to be built for scale, not just to “work once.” You need product data collected reliably, with structure for names, prices, URLs, images, sellers, availability, and category details. I’ve built scrapers for large catalogs and sites that actively limit requests. My focus is stability: controlled request rates, retries, caching, session handling, and clean data extraction that can keep running without constant babysitting. I’d design it to be modular so fields can be added without rewriting the whole scraper, and I’d make sure the output is consistent and easy to plug into your pipeline. If anti-bot measures appear, I handle them with practical, legitimate techniques rather than brittle shortcuts. If you want, I can map the scraping flow and outline the most reliable setup for Allegro. Best regards, Gabriel

Hello The hardest part is usually aligning data quality, evaluation, and production monitoring with real-world latency and compliance constraints. Integration with existing systems and clear ground truth often drive most of the early risk. What does the current stack look like for ingestion and deployment? Are there SLAs or compliance boundaries I should plan around? Is the work batch-only or does it require real-time inference? Looking forward to learning more about the architecture.
