I will build an n8n automation with ai agents, error handling and documentation


About this gig
Stop doing the same 20-minute task every day. I build n8n workflows, with AI where it actually helps, that run reliably, retry on failure and tell you when something breaks.
Popular builds
- Lead intake and AI qualification, then CRM update and Slack or Telegram alert
- Invoice, PDF or email extraction into Google Sheets, Airtable or a database
- Scheduled AI reports and daily briefings
- Form, then approval, then action
- Migration from Zapier or Make to n8n to cut monthly fees
Every build includes error handling, an error workflow with alerts, a credential-safe workflow export (JSON) and a walkthrough video. n8n Cloud or self-hosted; I run my own n8n instances in production.
Why me
Tech Lead of a live AI SaaS; 16 bots and workflows in production for small businesses in tourism, hospitality and spas. I write the custom JavaScript or Python node when no-code stops.
Message me with the process first. I will confirm scope and price within a few hours.
Not included: subscriptions for third-party apps and AI API usage.

FAQ
Do you work with n8n Cloud or only self-hosted?
Both. I build on n8n Cloud or on your self-hosted instance. If you do not have n8n yet, I can recommend the cheapest option for your volume or set up a self-hosted instance for you (see my other gig).
Can you migrate my Zapier or Make automations to n8n?
Yes. Send me the list of zaps or scenarios. A few simple ones fit the Standard package; larger or multi-app migrations are Premium or a custom offer. Each migrated workflow is tested against real data before handover.
What exactly do I receive at delivery?
The workflow deployed and running on your n8n instance, the workflow export (JSON) without credentials, a short written doc of how it works and how to change it, and a walkthrough video. Standard and Premium also include an error workflow with alerts.
Do you need my passwords or API keys?
No. You add credentials inside your own n8n instance (I guide you through it), or you give me a temporary user that you remove after handover. I never store your keys, and the exported workflow JSON contains no secrets.
