n8n Developer
Build powerful, self-hosted automations without the Zapier tax. We are n8n Developers who architect complex workflows, integrate custom APIs, and deploy scalable infrastructure.
What is an n8n Developer?
n8n is a fair-code workflow automation tool that is far more powerful than Zapier or Make. An n8n Developer writes JavaScript/TypeScript within nodes, manages self-hosted servers, and builds complex logic loops.
We don't just drag and drop. We treat automation as code. We use Git for version control, implement error handling, and optimize for high-throughput data processing.
Why choose zenrev?
- Self-Hosting Experts: We deploy n8n on your own cloud (AWS/DigitalOcean) to keep data secure and costs low.
- Custom Code: We write custom Function nodes to handle complex data transformation that standard nodes can't do.
- AI Integration: We are experts at chaining LangChain and OpenAI nodes within n8n to build agentic workflows.

How We Automate
Workflow Mapping
We diagram your current manual process and identify the API endpoints needed.
Infrastructure Config
We set up a dedicated n8n instance on your cloud or ours to ensure privacy.
Development
We build the workflow, writing custom code blocks for logic that standard nodes can't handle.
Error Handling
We implement robust error catching and notification systems (Slack/Email alerts).
Handoff & Training
We document the workflow and train your team on how to monitor and maintain it.
Example n8n Code
Custom JavaScript node for data transformation.
// Code Node: Transform API Response
const results = [];
for (const item of items) {
const rawData = item.json.api_response;
// Custom logic to normalize data
const normalized = {
email: rawData.contact_email.toLowerCase(),
company: rawData.org_name.trim(),
score: rawData.intent_score > 80 ? 'High' : 'Low',
timestamp: new Date().toISOString()
};
results.push({ json: normalized });
}
return results;Alt: JavaScript code snippet from an n8n Function node written by zenrev to normalize API data.

Frequently Asked Questions
What is n8n?
n8n is a workflow automation tool similar to Zapier but 'fair-code'. It allows for much more complex logic, custom code execution, and can be self-hosted to keep your data private.
Why should I use n8n over Zapier?
Cost and Complexity. Zapier gets incredibly expensive at scale. n8n is free if self-hosted. Also, n8n handles loops, complex branching, and custom code much better than Zapier.
Do you host n8n for us?
We can. We typically recommend setting up a private instance on your own cloud (AWS/DigitalOcean) so you own the data, but we manage the setup and maintenance.
Can n8n connect to my internal API?
Yes. n8n has a generic HTTP Request node that can connect to any REST or GraphQL API, including internal tools behind a VPN (if configured correctly).
Is n8n secure?
Yes, especially when self-hosted. Your data never leaves your server. We also implement best practices like securing webhooks and using environment variables for secrets.
Can n8n handle high volume?
Yes. n8n can be scaled with 'workers' to handle thousands of executions per minute. It is much more performant than cloud-only tools like Zapier.
Do you offer support after building the workflow?
Yes. We offer retainer packages to monitor, fix, and optimize your workflows as your business processes change.
Can n8n use AI?
Absolutely. n8n has native integrations with OpenAI and LangChain. It is one of the best platforms for building AI agents and RAG pipelines.
