Invoice Generation Platform (Personal SaaS Project) - Scalable invoice generation platform engineered for bulk asynchronous PDF processing using BullMQ & Redis.
Implemented CSV/Excel batch imports, customizable invoice templates, and secure cloud file storage with AWS S3. Built batch processing, automated retry mechanisms, and analytics for efficient generation.
Highlights & Pipeline:
- Asynchronous worker pool rendering pixel-perfect PDF invoices via headless Puppeteer.
- Bulk CSV/Excel client data parser with validation, chunking, and error reporting.
- Dead-letter queues, idempotent job scheduling, and exponential backoff retries with BullMQ.
- Encrypted multi-region document archival using AWS S3 pre-signed expiring links.
