Dave Riordan developed and delivered a suite of web scraping spiders for the alltheplaces/alltheplaces repository, focusing on extracting structured location data for grocery and restaurant brands. He implemented robust data extraction pipelines using Python, Scrapy, and regular expressions, normalizing addresses and hours to ensure consistency across datasets. In March, he built spiders for El Super US and Xi’an Famous Foods, handling end-to-end data parsing from sitemaps and individual pages. By May, he introduced a scalable, shared base class for Associated Supermarket Group brands, reducing code duplication and streamlining onboarding of new brands, which improved maintainability and expanded data coverage.

Month: May 2025 | Repository: alltheplaces/alltheplaces. Key deliverable: a scalable set of grocery store brand web scraping spiders built on a shared base class, consolidating common scraping logic and improving maintainability. Implemented brand-specific spiders for Associated Supermarket Group brands (Associated Supermarket, Compare Foods, Met Foodmarket, Pioneer Supermarket) configured with brand names and URLs to extract store location data, enabling broader data collection and actionable business insights. Impact: expanded data coverage across multiple brands, faster onboarding of new brands, reduced code duplication, and easier ongoing maintenance. Demonstrated Python OOP, modular scraper design, and config-driven architecture. Related commit: 44f36723589c9145f2df08885fc81165314a1b5c (Add spiders for Associated Supermarket Group brands) as part of (#13075).
