Work

I don't deal in hypotheticals. Here is what I've shipped.

Contact centers, WhatsApp engines and voice agents that agencies put their logo on and businesses run their intake on.

Full caller history on screen, smart routing with automatic voicemail after 20 seconds, and TaskRouter logic so one contact never opens duplicate tasks.
