About this gig
Native GoHighLevel automations break the moment your stack gets serious. Triggers misfire. Zapier bills climb. Webhooks time out. Leads slip through gaps no snapshot can fix.
That's not a GHL problem. That's an architecture problem.
I build production-grade backend systems inside GoHighLevel: custom apps, private API connections, resilient webhooks, and Make.com / n8n workflows that sync your entire tech stack in real time including Vapi AI voice agents routed straight into your pipelines.
What I engineer:
- Custom GHL apps & private API connections (bypass Zapier limits)
- Webhook builds with retry logic, error handling & payload mapping
- Make.com / n8n scenarios: lead routing, enrichment, bi-directional CRM sync
- Vapi & AI voice agent call routing into GHL pipelines & calendars
- HubSpot, Pipedrive, Zoho & Twenty CRM data mapping and migration
- Workflow audits: I find the broken trigger before it costs you a deal
Every build ships documented, tested against live payloads, and handed over with a Loom walkthrough so your team owns it fully.
Stop patching automations with duct tape. Message me your stack I'll map the fix before you order.

FAQ
Why a custom API connection instead of just using Zapier?
Zapier adds per-task cost, latency, and payload caps. A direct connection gives real-time webhooks, custom retry logic, and zero per-task fees — it usually pays for itself in one month of Zapier bills.
Can you work under NDA or inside my white-label SaaS mode?
Yes — NDA-friendly, and I build inside SaaS Configurator / white-label setups without breaking your branding or billing.
Can you sync GHL bi-directionally with HubSpot, Pipedrive, Zoho, or Twenty CRM?
Yes — field-mapped, deduplicated, two-way sync with conflict rules e.g., last-write-wins or per-field precedence so neither system overwrites the other.
Can the voice agent book directly into GHL calendars with round-robin?
Yes — function-calling checks GHL calendar slots in real time, respects round-robin and team availability, and fires confirmation SMS/email from GHL.
How does Vapi call routing actually land inside GHL?
The Vapi assistant fires a server-side webhook on call end or mid-call function call that pushes transcript, summary, and disposition into GHL via custom-app API — creating/updating the contact, tagging, and booking the calendar appointment automatically.
Can you rebuild my messy Zapier Zaps into Make.com or n8n to cut costs?
That's a specialty. I map your current Zaps, rebuild them as modular Make scenarios (routers, iterators, error handlers) or self-hosted n8n workflows — typically cutting operation spend 60–80%.
How do you handle GHL API rate limits (429 errors)?
Queue-based throttling with exponential backoff and batch endpoints where available; Make/n8n scenarios use sleep + iterator patterns so bulk syncs never hit the 429 wall. Do you test against live payloads before delivery?
How do you make webhooks reliable — what happens when an endpoint fails?
Every webhook ships with retry/backoff logic, signature verification where supported, idempotency keys to prevent duplicate contacts, and a dead-letter alert (email/Slack) so silent failures never go unnoticed.
Can you build a GHL marketplace app, or is this private-app only?
Private/integration apps for your sub-accounts and agency use. Marketplace submission is out of scope, but I structure code so it can be productized later.
