01 About

Jonathan Rebullo

Six years in sales gave me a front-row view of how businesses actually run: where handoffs fail, where leads stall, and where hours disappear into repetitive tasks.

Today, I’m an AI Automation Specialist. I design and build systems that replace manual steps with automated workflows.

I build AI agents, RAG chatbots, CRM integrations and multi-step automations using n8n, GoHighLevel, LLMs, APIs and webhooks, connecting the tools a business already uses so information moves on its own.

My approach: understand the problem, map the process, build the solution, test it, and document how it works.

My goal is simple: automate repetitive work so people can focus on what matters most.

02 Selected work

Systems that turn inquiries into booked appointments

AI agent · Lead capture · CRM

Messenger AI Lead Agent → GoHighLevel

A Messenger AI agent that answers property questions, collects a buyer's details, confirms them, and saves the lead to GoHighLevel with a note and a follow-up task.

OutcomeOne Messenger conversation becomes a confirmed CRM lead: contact, pipeline deal, note and follow-up task, with no manual data entry.

  • Messenger webhook in n8n, with Meta's verification handshake
  • AI agent (Google Gemini) that answers from the project's information in Google Docs, with conversation memory
  • Lead capture tool the agent calls only after the customer confirms their details

GoHighLevel CRM · Real estate sales

GoHighLevel CRM Pipeline Management

A real estate sales pipeline where every deal has an owner, and each agent sees only their own leads.

OutcomeEvery deal has one owner and a clear stage across a 6-stage pipeline, and each agent sees only their own leads (2 of 6 in testing).

  • Real estate sales pipeline, from New Lead to Site Viewing
  • Restricted data visibility: agents see only their assigned contacts and deals
  • An owner on every deal

GoHighLevel CRM · Lead automation

GoHighLevel CRM Lead Automation

Property inquiries from a GoHighLevel form become contacts and pipeline opportunities automatically, with no manual data entry.

OutcomeA new inquiry becomes a CRM contact and a pipeline deal within 3–5 seconds, with no manual data entry.

  • Property inquiry form with a required property type field
  • Contact created automatically from each submission
  • Workflow that creates a sales opportunity in the pipeline

06 FAQ

Common questions

What kind of work do you automate?

Repetitive business tasks: capturing and following up on leads, booking appointments, updating CRM records, answering common customer questions and moving data between the apps a business already uses.

Can you build an AI voice agent that books appointments?

Yes. My AI Voice Appointment Setter uses Vapi, n8n and Google Calendar to check availability and book, reschedule or cancel appointments during the call, and logs each booking to Airtable. Recorded test runs are in the Selected work section.

Which tools do you work with?

n8n, GoHighLevel, Zapier, Make.com, Vapi, OpenAI, Gemini, Claude, OpenRouter, Supabase, Airtable and Google Workspace, connected through APIs and webhooks.

What do you set up in GoHighLevel?

Sales pipelines and stages, forms that send leads into the CRM, opportunities, user roles and permissions, and lead assignment. My two GoHighLevel projects show a real estate pipeline from new lead to site viewing.

Which businesses is this a good fit for?

Businesses that depend on leads and appointments, such as real estate teams, agencies and service businesses. My six years in sales shape how I design lead capture, follow-up and booking flows.

Can you work with clients outside the Philippines?

Yes. I work remotely from the Philippines (UTC+8). You can book a call from this page, and the booking page shows open times in your own time zone.

How does a project start?

With a short discovery call to map your current process and pick the bottleneck worth automating first. I then build and test the system in your tools, and hand it over with documentation.
