What I'm looking for

I’m looking to support high-performance teams by streamlining operations, managing complex calendars and inboxes, and automating repetitive work with Zapier/Make/n8n—so fewer tasks fall through and everyone can focus on results.

I'm an Automation & AI Operations Specialist who builds systems that make teams work faster with less effort.

In customer operations, I improved first-contact resolution by 12%, reduced repeat inquiries by 18%, and increased CSAT by 20% through proactive case management and Zendesk escalations.

On the automation side, I've built and deployed workflows across Make, n8n, and Zapier — cutting manual work by 38% — with AI integrations using Claude and GPT-4. Projects include a live FAQ chatbot (Claude API + Node.js), a scheduling agent, and automated guest communication flows. I work comfortably with webhooks, JSON, Google Workspace, Airtable, and Notion.

Available immediately for remote roles in automation, AI ops, or executive support.
