Aggregating US municipal building permits across different counties into a unified lead feed using Python automation pipelines.
The real bottleneck in municipal scraping isn’t parsing HTML — it’s the fragmentation of municipal portal architectures (legacy ASP.NET, dynamic GIS viewers, and session-locked forms).
How we structured the pipeline:
• Asynchronous crawling pipelines with request queuing
• Normalized schema parser converting raw permit tables into structured JSON
• Automated deduplication engine running on daily trigger workflows
