Executive Architecture Summary
Fault-tolerant data extraction and pipeline engine processing daily multi-gigabyte client reporting feeds.
The Challenge Manual data entry and fragile overnight Python scripts caused frequent data corruption and delayed client reporting by up to 36 hours.
Architectural Solution - Implemented a queue-backed Node.js and BullMQ worker pipeline with automated exponential backoff retries. - Integrated schema validation via Zod to quarantine corrupted inputs before database insertion. - Created an automated notification webhook for Slack alerts and Prometheus telemetry.
Measurable Impact - **Cost Savings**: Saved client $48,000 annually in manual developer intervention hours. - **Delivery**: Report generation time dropped from 36 hours to under 8 minutes.
