[ overview ]
Ping by Blutec is a production WhatsApp marketing platform built on the official WhatsApp Business API — broadcast to thousands, let AI answer the replies, and surface the leads worth calling. I optimized the bulk-messaging backend and high-volume send queues so campaigns of 10,000+ contacts deliver reliably under WhatsApp's rate limits.
[ what it does ]

- Lead and engagement scoring that routes qualified contacts to the sales team
- Shared team inbox with agent assignment and internal notes
