I will fix n8n errors, optimize workflows and debug ai agents
Mariia Luna
About this gig
Is your n8n workflow breaking, throwing JSON errors, or stuck in AI loops?
I debug, fix, and optimize n8n workflows and AI agents so they run reliably without silent failures. With hands-on experience building and debugging production RAG systems, I fix the specific errors most freelancers miss.
️ What I Fix:
- Structured Output & JSON parsing failures
- AI Agent iteration limits & execution loops
- Telegram Parse Mode & formatting errors
- Vector Store & Embedding mismatches
- Duplicate escalation loops & webhook routing
- API/HTTP node authentication errors
- Error handling & Slack/Telegram alerts
Why Me?
1. Root-cause fixes, not temporary patches
2. Added fallback logic for reliability
3. Fast diagnosis with clear explanations
How It Works:
1. Send your n8n error log or workflow .json
2. I find the root cause and propose a fix
3. I debug, test, and deliver the working workflow
I don't just connect nodes I design for what happens when they break.
Contact me before ordering with your error details!

Hi! I’m Maria. With a background in HR Ops & data analysis, I build practical n8n AI Agents grounded in real business operations — from onboarding systems to support bots.
Unlike pure devs, I view automation through business workflows and error-proofing.
What I build & fix:
• Custom RAG AI Agents (Gemini, Claude, OpenAI)
• Support & Lead Bots with Human Escalation
• HR & Internal Operational Automations
• Workflow Debugging, API Fixes & Error Handling
I don't just connect nodes — I design for what happens when they break.

FAQ
How do I share my n8n workflow with you for debugging?
You can export your workflow as a .json file from n8n and send it to me, or grant temporary access to your self-hosted / n8n Cloud instance.
What if the error cannot be fixed due to an external API limitation?
I will identify the root cause, document the external limitation, and build a work-around or fallback handling so your workflow fails gracefully without breaking down.
Can you fix AI Agent execution loops and JSON parsing errors?
Yes! I specialize in fixing AI agent issues, including output format mismatches, conversation memory/context issues, system prompt guardrails, and vector store connection errors.
