About this gig

Your n8n workflow runs fine in the editor and breaks in production. That is the part I fix.

I run self-hosted n8n in production, including a WhatsApp AI ordering agent that handles real customers every day. The workflow is public on my GitHub, so you can inspect how I build before you hire me.

WHAT I FIX MOST OFTEN

  • Webhooks that get verified but never receive a payload
  • Nodes that work on one item and break on a list, because the loop was missed
  • Credentials and OAuth that expire silently and take the automation down
  • Missing error branches, so one bad record kills the whole run
  • Rate limits and timeouts that only appear under real volume
  • AI agent nodes that return prose instead of parseable JSON

WHAT I BUILD

API integrations, HTTP request nodes with proper auth, database reads and writes, scheduled jobs, human approval steps, alerts to Slack, Telegram or email.

You get the fixed workflow as an importable JSON, plus a written note explaining what was wrong and why. If the cause turns out to be outside n8n, I tell you straight away instead of billing for guesswork.

I never ask for your password or 2FA code. You add me as a user, or we work over screen-share with you in control.

I'm a full-stack developer from Brazil who builds AI automation that survives production, not only a demo. My focus: WhatsApp Cloud API and AI agents on n8n. I built a complete restaurant ordering agent that reads the menu, takes the order, calculates the total and hands the chat to a human when it should. The workflow is public on my GitHub, so you can see how I work before hiring me. I also build web systems end to end: React, Node.js, PostgreSQL, Supabase, self-hosted n8n. If your WhatsApp API is stuck on a Meta error, or your automation breaks in real use, that is what I fix.
