About this gig
n8n automation | n8n AI agent | n8n workflow | WhatsApp automation | AI chatbot
I fix n8n workflow errors and build n8n ai automation that keeps running after handover. Most n8n workflows fail on day forty, not day one, and nobody notices. n8n has no built-in alerts.
FIX :
Execution stopped at this node
n8n may have run out of memory
Problem running workflow / Connection Lost
JSON, data mapping and expression errors
Allocation failed JavaScript heap out of memory
n8n webhook error, webhook not firing, expired credentials, broken triggers -
Workflows broken after the n8n 2.0 upgrade
BUILD n8n automation:
n8n ai agent with memory, RAG and multi-agent routing
WhatsApp chatbot with lead qualification and human handoff
n8n lead generation: capture, scoring and routing pipelines
n8n crm integration: HubSpot, Salesforce, Pipedrive, Shopify, Zapier
Content automation, OpenAI and API integration
MCP server so Claude or GPT can run your workflows as tools
I work with n8n Cloud and self-hosted n8n. Standard and Premium solutions can include error alerts, and execution logging for more reliable automation.
MESSAGE ME FIRST. Send your error or a screenshot of your workflow

FAQ
My n8n webhook is not firing. Can you fix it?
Yes. Usual causes: the webhook URL changed on the sender side, the workflow is inactive, a test URL is live in production, a signing secret rotated, or a tunnel dropped on self-hosted. Send me the execution log and I will identify it before you order.
n8n says execution stopped, out of memory. What causes that?
Usually an unpaginated API call pulling thousands of records, a synchronous loop making N times M requests, or heavy JavaScript expressions. I refactor with Split In Batches, cursor-based pagination and controlled parallel execution. Diagnosis first, fixed quote second.
I upgraded to n8n 2.0 and my workflows broke. Do you handle migration?
Yes. The v1 to v2 migration removes the legacy Start node and breaks the Python code node and subworkflow node. I audit on a staging clone, send a written break-list with a fixed quote, then repair. Your live instance is untouched until you approve.
How will I know if my n8n workflow fails after delivery?
Within seconds. n8n has no built-in notification system, so failures are silent by default. Standard and Premium include an Error Trigger with Slack or email alerts, retry logic with fallback branches, and execution logging to Sheets or Postgres.
What is an n8n MCP server and do I need one?
It exposes your workflows as callable tools, so Claude or GPT can run them directly instead of only answering questions. You need it if you want an AI assistant that books, updates or sends things. If you only need scheduled automation, skip it.
Can you build an n8n AI agent with memory and RAG?
Yes. Agent node with conversation memory, a RAG knowledge base over your documents, tool calling, and multi-agent routing that sends simple queries to a light model and complex reasoning to a stronger one. That routing alone cuts running cost sharply.
Can you build a WhatsApp AI chatbot with n8n?
Yes. WhatsApp Business API connected to n8n, AI responses, lead qualification questions, CRM write-back, and human handoff when the bot cannot answer or the lead is hot. Telegram and web chat work the same way.
Do you work with self-hosted n8n and can you secure it?
Yes, self-hosted and Cloud. Over 60 percent of self-hosters hit failures, downtime or a security incident within 30 days, almost always from skipped security config and no backups. I check environment variables, credential storage, access control and backups.
Should I use n8n, Zapier or Make for my automation?
n8n if you need AI agents, custom code, self-hosting or high run volumes, since it does not bill per task. Zapier for simple two-app triggers. Make sits between. If n8n is wrong for your case I will say so before you order, not after.
What do you need from me to start, and how fast can you deliver?
n8n access or a workflow JSON export, the exact error or execution log, credentials for the apps involved, and one sentence on what should happen. Fixes ship in 2 days, 24-hour rush available. Missing access is the main cause of delays.
