I will build gohighlevel custom apps, ghl api highlevel integration and ai automation
Fullstack engineer shipping software that just works
About this Gig
GoHighLevel custom app development: I build the software GHL cannot do natively, then wire AI into it.
Private and Marketplace apps, API integrations, and the workflows and dashboards around them. Engineered, not glued together with Zapier.
What I build:
- Private GHL apps: OAuth 2.0 install flow, token refresh, encrypted token storage
- HighLevel API v2: contacts, opportunities, conversations, calendars, payments
- Webhooks both ways: signature checks, retries, idempotency, dead-letter logging
- Middleware and queues in Node, Python or Next.js with Postgres or Supabase
- Dashboards, portals and GHL workflows on live data
- Snapshot packaging and rollout for sub-accounts
- AI on top: conversation AI, chatbots, voice agents, knowledge base from your docs
- Sync and migration from legacy CRMs, Sheets, Airtable or database
I map the data model, build in a staging sub-account, then hand over repo access, a Loom and docs. Rate limits, pagination and failed calls are handled in the build, not in a follow-up ticket.
I'm a software engineer first. If it has an API, I can make GHL talk to it.

FAQ
Can you build a private app only my agency uses?
Yes. Private apps install on your agency or sub-account without Marketplace review, and only your team sees the tab.
Do you build public GoHighLevel Marketplace apps?
Yes. OAuth 2.0 install flow, custom pages, scopes and submission-ready packaging, built to pass review.
Have you shipped an app through Marketplace review?
Yes. I handle the install flow, scopes and the submission itself, and I know what reviewers push back on.
