About this gig
Broken webhooks, unexpected API rate limits, and unhandled JSON exceptions drain team productivity. When an automation node fails silently, sales pipelines freeze and client records get lost.
I troubleshoot, refactor, and harden n8n workflows and AI agent integrations into producton grade deterministic, self-healing pipelines.
What I Fix:
1- Failing HTTP Request nodes, webhook timeout errors, and OAuth credential drops
2- Complex JSON schema mismatches, loop crashes, and sub-workflow memory leaks
3- Context window overflow and LLM prompt timeouts on LangChain/n8n nodes
4- Bloated OpenAI/Claude API token consumption via semantic caching and payload trimming
5- Flaky Make/Zapier connections migrated safely into self-hosted or cloud n8n instances
Every resolution includes clean node labeling, execution logging, and fail-safe fallback branches so the same error never brings your business to a halt again.
Share your workflow JSON export or error screenshot for an immediate assessment.
Message me your problem , workflow JSON and a screenshot of your failing node for a free 10-minute architecture assessment before ordering.

FAQ
Q: What information do you need to start debugging my broken n8n workflow?
A: I need access to your n8n workflow JSON export or access to your n8n environment, along with a description of the error and execution logs showing where the failure occurs.
Q: What if my workflow breaks again after delivery?
A: Every package includes a 30-day structural guarantee. If the specific nodes, Webhooks, or scripts I fixed fail or throw errors within 30 days, I will repair them free of charge.
Q: Can you take over a messy, undocumented workflow built by another developer?
A: Yes. I excel at untangling complex legacy systems. I map out the existing data logic, identify structural weak points, and rebuild it using optimized, modular node sequences.
Q: How exactly do you lower my monthly AI model API expenses?
A: Many setups pass repetitive or massive payloads to LLMs unnecessarily. I optimize workflow token efficiency by trimming data inputs, refining prompt sizes, and adding smart data caching layers so you only pay for what you actually use.
Q: Can you migrate my unstable Zapier setups directly into n8n?
A: Yes. I routinely execute zero-downtime platform migrations, turning restrictive multi-step Zapier chains into flexible, cost-efficient, and highly advanced n8n workflows.
What do you need to begin debugging immediately?
An exported n8n workflow JSON file or temporary workspace access, along with an execution log screenshot detailing the failing node.
Do you provide a post-delivery warranty?
Yes. Every bug fix package includes a 14-day warranty covering any regressions on the specific nodes or logic I refactored.
Can you work on self-hosted Docker and VPS environments?
Yes. I regularly troubleshoot n8n deployments hosted on AWS EC2, DigitalOcean, Hetzner, GCP, and n8n Cloud.
