The solution established a resilient collection layer between third-party delivery marketplaces and downstream analytics, with each stage designed to maintain access, consistency, and freshness as order activity changed throughout the day.
Multi-Platform Order Collection
A distributed Scrapy-based architecture collected merchant-side order activity from DoorDash, Uber Eats, and Grubhub. Parallel spider execution supported continuous extraction while structured item definitions provided a common format for records originating from different platforms.
Resilient Platform Access
Undetected Selenium, Selenium Wire, and rotating Zyte proxies were combined with randomized request behavior to manage platform access. This layered approach helped the collection process adapt to bot detection, rate limits, and IP restrictions without relying on a single access method.
Automated Session Management
Merchant authentication was maintained through cookie-based sessions, automated cookie generation, refresh mechanisms, and fallback re-authentication. Credentials were managed separately from application logic, allowing long-running collection jobs to recover when individual sessions expired.
Standardized Data Processing
Incoming records passed through normalization, schema validation, duplicate detection, and quality filtering before export. Platform-specific formats were converted into consistent order structures, reducing downstream cleanup before analytics use.
Continuous Data Refresh
Cron-based orchestration triggered collection every minute, while flock prevented overlapping runs. Incremental processing focused each cycle on newly available activity instead of repeatedly rebuilding complete datasets, helping maintain near-real-time updates efficiently.
Analytics-Ready Storage
Validated records were exported through structured CSV and JSON workflows and loaded into BigQuery for centralized analysis. This created a scalable data foundation for examining delivery activity across restaurants, platforms, and broader operational trends.
