Problem
Teams need secure WhatsApp operations at volume. Shared logins, brittle scripts, and one-off tools fail on org isolation, rate limits, encrypted credentials, and reliable message queues.
Approach
We are building ChatBridge as a full-stack sub-brand: Next.js operations UI, Rust/Axum API, PostgreSQL, Redis for rate limiting and auth cache, Postgres-backed message workers, S3-compatible media, self-hosted n8n, and Nginx as reverse proxy. Migrations stay an explicit ops step.
Solution
Org-scoped APIs use X-Organization-Id. Access is JWT + RBAC (Super Admin, Business Admin, Team Member). WhatsApp account tokens are encrypted with AES-256-GCM. TOTP covers 2FA. Message work runs through durable queue jobs, with n8n for longer automations.
Outcome
Ongoing sub-brand build — multi-tenant architecture, security model, and messaging API layers are in active development.
