Jobs
1

Hi everyone,

I’m an AI Automation Engineer available for hire (per project or full time). I build and maintain production automation systems. ~2 years building this stuff full-time.

What I build:

  • n8n workflows with proper error handling, retry logic, and Slack alerting - JavaScript-heavy

  • AI content pipelines (e.g. an end-to-end AI UGC video system: LLM script generation → task creation → video generation → multi-account social posting)

  • RAG systems (Google Drive ingestion → parsing → vector db → query API with reranking)

  • API integrations across CRMs, project tools, and accounting — HubSpot, ClickUp, QuickBooks, Google Workspace, Slack, GoHighLevel, Google Ads

  • Two-way data syncs with the messy edge cases handled (OAuth refresh, SyncTokens, dedup, idempotency)

My stack:

  • n8n, Python scripts, Zapier, Make.com

  • LLM APIs: Claude, Gemini, OpenAI

Background:

Pricing:

  • Hourly: $20–28/hr depending on scope
