Hire an n8n
developer.
I'm Ergini, a senior developer who builds AI-powered automation on n8n - self-hosted deployments, custom nodes, and LLM-driven workflows that make real decisions. When the canvas runs out, I drop into code. Working across Europe on CET.
What I build
AI-powered workflows
n8n flows where OpenAI or Claude does the reasoning - classification, extraction, drafting, routing - with structured outputs and guardrails.
Self-hosted n8n setup
Docker or Kubernetes deployment, queue mode for scale, backups, secure credentials, and EU data residency where you need it.
Custom nodes and code
Typed custom nodes in TypeScript and code steps for integrations and logic the visual catalog cannot express.
System integrations
Connect your CRM, database, email, Slack, docs, and APIs into reliable end-to-end automations with error handling and retries.
AI agents on n8n
Webhook- or schedule-triggered agents that call tools and route through human approval on the actions that matter.
Audits and rescue
Fix fragile flows, add monitoring and error handling, and re-architect automations that have grown into spaghetti.
Stack
How engagements work
- 01
Discovery call (free, 30 min). You describe the process to automate, I ask hard questions, we both leave with a clear picture of what's needed.
- 02
Written scope and quote (3 days). Fixed-scope where possible, milestones, deliverables, and a price you can sign.
- 03
Build (1-8 weeks). You see workflows running and demoed as they land, not at the end.
- 04
Ship and handoff. Deployment, monitoring, docs. Optional retainer for ongoing changes at $100/hr.
Frequently asked questions
What can you build with n8n?
Multi-step automations that connect your tools and let an LLM do the reasoning: lead enrichment and routing, document processing, support triage, onboarding flows, reporting, data sync between systems, and AI agents triggered by webhooks or schedules. When a workflow outgrows the visual canvas, I drop into custom code or custom nodes rather than fighting the tool.
Should I self-host n8n or use n8n Cloud?
Self-hosting wins on cost at volume, data control, and unlimited executions - which matters for EU teams with data-residency needs. n8n Cloud wins on zero ops. I set up either, and for self-hosting I handle the Docker or Kubernetes deployment, backups, queue mode for scale, and secure credential storage.
n8n vs Zapier vs Make - which should I use?
n8n wins for developers, self-hosting, and AI-heavy workflows; Zapier wins for non-technical teams; Make sits between them. I break down the per-execution cost math and the AI capabilities in my n8n vs Zapier vs Make comparison. I will recommend the honest fit for your case, even if it is not n8n.
Can you add AI and LLM steps to my workflows?
That is my specialty. I wire OpenAI and Anthropic Claude into n8n with proper prompting, structured outputs, retrieval over your data, and guardrails - not a naive single prompt node. The result is a workflow that makes reliable decisions, with human-in-the-loop approval where the stakes are high.
Can you write custom n8n nodes?
Yes. When your integration is not in the catalog or needs custom logic, I build typed custom nodes in TypeScript, test them, and deploy them to your instance. This is where most n8n freelancers stop and a senior developer keeps going.
How much does n8n work cost?
A focused automation build is typically $3.5K-$15K. A larger system with self-hosted deployment, custom nodes, and AI steps runs $15K-$60K. Hourly is $100/hr. Scoped after a free 30-minute call.
