I build the automation layer that runs a company: n8n, AI agents and GoHighLevel, connected into one system.

Most automations work in the demo and break by month three: no error handling, no logging, nothing documented, and nobody notices until a client complains. I build for the opposite. Systems running thousands of executions per day, with retries, monitoring and documentation your team can run without me.

What I build:

• n8n automation (Python) and AI agents, cloud or self-hosted
• AI voice agents for lead qualification and support (Retell, Vapi, Twilio)
• GoHighLevel CRM architecture and white-label multi-account environments
• CRM migrations and secure API integrations
• Marketing, sales and revenue operations reporting

Recent work:

• Enterprise automation processing thousands of workflow executions per day with n8n, Python and AI
• AI voice agents integrated with GoHighLevel, Retell AI and Twilio, from call trigger to CRM update
• Multi-office GoHighLevel infrastructure for a US legal marketing company: lead routing, commission management, reporting
• Tracking audit for a Shopify brand: found 11 tags reporting to a placeholder ID and ~26% of revenue with no identifiable source

How I work: baseline before any change, one change per release, a rollback plan, and documentation at handoff.

I don't build disconnected automations. I build secure systems companies can grow on.
