Cover image for Lead capture form built via
Lead capture form built via Playwright CLI automation — First Name, Last Name, Phone, Email, with TCPA-compliant consent checkboxes auto-generated by GHL. Connected to a speed-to-lead workflow that fires an automated response within 90 seconds of every form submission. Built programmatically, no manual GHL form builder clicks needed.

Cover image for This is the “Agency New
This is the “Agency New Client Onboarding” workflow built entirely by GHL’s Workflow AI from a plain-text description I wrote. It fires the moment a client signs — sending a welcome SMS, onboarding email with intake form, creating a review task for the account manager, and notifying the owner. Zero manual setup on delivery day. The same workflow deploys to any agency client in minutes.

Cover image for Built automated sales and client
Built automated sales and client lifecycle pipelines inside GoHighLevel using Playwright CLI scripts — no manual clicking required. The HVAC pipeline captures leads and moves them from inquiry to booked job automatically. The agency pipeline detects at-risk clients before they churn and fires alerts to the team. Both were built and deployed in under 3 hours using Claude Code + GHL automation.
