the problem

Marketing teams needed to manage customer conversations, broadcasts, automation, and reporting across channels without stitching together separate tools or losing operational visibility.

technical context

  • Campaigns and support conversations needed to share customer, channel, and delivery data across the platform.
  • The platform had to isolate workspaces while handling asynchronous delivery events and third-party API constraints.
  • WhatsApp Business onboarding depended on Meta account setup and embedded signup workflows.

my role and technical scope

I led engineering delivery across onboarding, messaging, automation, analytics, and Meta Business API integration for a multi-tenant WhatsApp and email platform.

architecture and engineering decisions

  1. Used tenant-aware workspaces for teams, permissions, channel connections, and campaign data.
  2. Integrated Meta embedded signup and Business API flows into the platform onboarding path.
  3. Connected broadcasts, chatbot automation, live chat, webhooks, and analytics to shared customer workflows.
  4. Included campaign delivery visibility so operators could inspect outcomes across channels.

Third-party messaging APIs make retries, webhook handling, connection health, and failure visibility core parts of a reliable multi-tenant platform.
