01 // intro
I design production n8n workflows for operators across DACH — invoicing, CRM, support, and the unglamorous glue that actually keeps running.

03 // about
Peter H. builds n8n systems for operators who are done babysitting spreadsheets and glue-code. The brief is almost always the same: take the process everyone already knows, make it reliable, and leave a runbook a colleague can actually use.
Based in Cologne, DE. Work happens in German and English — DATEV and lexoffice as comfortably as HubSpot and Stripe. The preference is fewer workflows, stronger contracts, and alerts that mean something.
Background in music, tooling, and the unglamorous side of shipping. Automation is the craft now: production systems, not demo canvases.
