I build production automation systems for real businesses: event-driven pipelines that connect ordering platforms, documents, AI models and communication channels — running on self-hosted infrastructure I administer myself.

- Business impact first — I measure automations in hours saved and errors eliminated, not in node counts
- Production discipline — idempotent pipelines, encrypted credential stores, error handling, versioned workflows, data-retention policies
- Self-hosted by default — Linux VPS, Docker, Nginx, cron; full control over data and costs
