Overview & Scope
Configured and hosted a private, self-hosted deployment of the n8n visual workflow automation engine to connect cloud endpoints, automate databases, and orchestrate server operations.
Self-Hosted API Orchestration
Commercial middleware integrations (like Zapier) can become expensive and introduce compliance issues when handling sensitive data. This self-hosted n8n instance acts as a secure, local middleware service:
- Webhook Handlers & Transformations: Captures and processes asynchronous webhooks, running custom JavaScript nodes to filter, clean, and format JSON payloads before sending them to target APIs.
- Database & File Synchronization: Connects to local PostgreSQL databases, running cron-scheduled synchronization tasks to back up user profiles and verify file integrity.
- Server Monitoring & Notifications: Tracks server health parameters, triggers notifications to personal chat clients upon CPU/RAM spikes, and reports the completion of offsite cloud backup routines.
- Zero-Dependency Integrations: Offers complete control over data paths, ensuring that all operational logs and credentials remain securely locked within the private server network.
Core Deliverables
- Self-hosted node-based workflow server for complex API integrations.
- Asynchronous webhook processing, data transformations, and scheduled runners.
- Custom JavaScript nodes for filtering and preprocessing API payloads.
- Persistent storage and queue management backed by PostgreSQL.
- Automated monitoring pipelines alerting on server metrics and backup completions.
