Aside left
What?
Set up various workflow orchestrations for personal tasks on an n8n instance self-hosted on GCP, with:
- 20+ Node Types & Integrations: Includes diverse n8n capabilities including API integrations (GitHub, OpenWeatherMap), data processing (JavaScript, conditional logic, batch operations), scheduled execution, and data storage (n8n Data Tables, BigQuery)
- Multi-Source Data Aggregation & Reporting: Multi-workflow automation systems including master/child workflow patterns for scalable operations, with 30+ node workflows handling parallel data collection, conditional logic, and error handling
- Error Handling: Designed instance-wide error monitoring using Error Trigger workflows that capture failure details (stack traces, last node, retry info) and deliver actionable alerts via Gmail integration
- Workflow Backup & Version Control: Implemented automated GitHub-based version control for n8n workflows with intelligent change detection, comparing JSON structures to determine “new/different/same” states and auto-committing workflow updates with appropriate metadata
- Infrastructure as Code: Full GCP infrastructure (Cloud Run, Cloud SQL/PostgreSQL, Secret Manager, BigQuery, Cloud Scheduler, IAM) defined and managed with Terraform
Workflow outputs include*: custom graph of cloud costs, AI summary of news/sport, local weather warnings, local flood status as a custom graph, email notifications for new software versions and infrequently updated rss feeds, auto publish summary (static html) to Cloudflare worker, auto backup n8n workflows to github.
Why?
Build expertise with no-code workflow automation tool. Familiarise with GCP, as I’d mainly used AWS previously. Save time on recurring tasks.
