I will build n8n automation, n8n workflow, n8n ai agent with error handling


About this gig
Zapier costs too much. Make.com gets complicated fast. n8n sits in a different category open-source, self-hostable, no per-task fees, and built for businesses that actually run volume.
I build n8n workflows that work in production. Not templates, not copy-paste setups. Custom logic, proper error handling, and documentation you can actually use so you're not dependent on me after delivery.
What I build:
- Lead capture flows form to CRM to follow-up email, fully automated
- Data sync across Google Sheets, Airtable, HubSpot, Salesforce, and Notion
- AI agents using OpenAI, Claude, or Gemini classify data, draft replies, qualify leads, route tickets
- Zapier or Make.com migration (most clients cut monthly costs by 80% in the first month)
- Webhook-based integrations for tools with no native n8n node
- n8n self-hosted setup on your VPS or cloud server
What you get with every delivery: Complete workflow JSON, written documentation, and a Loom walkthrough video. Every build includes error handling and retry logic no silent failures, no broken workflows you find out about a week later.
One client was paying $300/month on Zapier. They're now on $10/month hosting n8n themselves. That's not unusual!

FAQ
What's the difference between n8n, Zapier, and Make?
n8n gives unlimited executions with no per-task fees. Zapier and Make charge per task, which gets expensive fast. n8n also supports custom code for complex logic. Most clients cut costs 80% after migrating.
Do I need to self-host n8n or can you set up cloud hosting?
Both work. I'll set up self-hosted n8n on your VPS via Docker for zero ongoing fees and full data control, or build on n8n Cloud if you prefer managed hosting. I'll recommend the best fit for your volume and comfort level.
How do you handle security and API keys?
API keys are stored encrypted in n8n's credential system, never in workflow code. For self-hosted setups I configure environment variables and secure credential management. Your data stays in your control throughout.
What kind of post-delivery support do you provide?
Every package includes a 14-day bug-fix guarantee, written documentation, and a Loom walkthrough so you can maintain it yourself. For ongoing needs, monthly retainer plans are available.
Can you integrate custom or niche APIs that don't have native n8n nodes?
Yes. I use HTTP Request nodes and custom JavaScript/Python to connect any API, even poorly documented ones. If your tool has an endpoint, I can integrate it no native node required.
How do AI agents work and what are the LLM costs?
AI agents call models like OpenAI or Claude to qualify leads, draft replies, or route tickets. You pay the AI provider directly — typically $20–100/month for normal volumes. I optimize prompts to keep token costs low.
