CRM with WhatsApp service

A project of my own, built to solve a problem I kept seeing up close: client conversations scattered across each team member personal WhatsApp.

Challenge

Client conversations lived in each team member personal WhatsApp. No shared history, no pipeline, no way to know what had been promised to whom. When someone left, the relationship left too.

Delivered

I built the CRM with a pipeline, per contact history and WhatsApp API integration, plus a worker for asynchronous message processing and object storage for attachments.

Result

It never became a product I sold, and that is fine: it is where I learned WhatsApp integration, asynchronous message processing and attachment storage by doing.
