Two LLM roles wired into a sales-management platform: an analyst on the management dashboard, a sales assistant on the B2B portal. Both answer only from the KPI API - the model never writes a number it did not fetch.
A Symfony service that keeps price and stock consistent across Amazon, Shopify and Walmart. One adapter interface per marketplace, a Workflow state machine per item, and a dead-letter queue for everything that fails.
Order, product and price feeds land through RabbitMQ into Laravel workers, get validated and transformed, and settle into partitioned PostgreSQL tables with Redis in front of the hot data.
Inbound Telegram messages go through classification and entity extraction, get scored for priority, and arrive in the CRM as complete lead records. The sales team opens a queue, not an inbox.

$ composer require serhiilabs/video-stream-guard Self-hosted on your infrastructure, with SSO, project RBAC, secret rotation, backups with a tested restore, and SLA reporting that tells you before your users do.
n8n's native security audit plus five checks it does not cover, diffed against last week and delivered to Telegram.
The n8n API and Data Tables over a rolling window, with a degradation threshold that flags a workflow before its users do.

n8n-automationA self-hoster's map of n8n user management across Community, Business, and Enterprise. Where the real paywalls sit, which capability forces which tier, and the one place the docs and the license check disagree.
n8n-automationSelf-hosted n8n holds three different secrets, not one. A practical guide to where each lives, who can reach it, how it rotates, and which controls are gated behind paid tiers.
Send me what breaks today. You get an honest read on whether automation is the answer - and what it would take.
