À propos de moi
I build n8n automations that don't break in production — and when n8n hits its limits, I write the code to push past them. 6+ years backend engineering (Java, including projects for BMW and Mercedes). Now focused on n8n: self-hosted setups, custom code nodes, AI agent workflows. What's different: I write actual code (JS/TS/Java), set up proper Docker and monitoring, and every workflow ships with error handling most freelancers skip. Part of "Thanks, Robot studio" — team backup for bigger projects. Response under 2h, EU business hours.... Plus d’infos
